The cleansing of the stomach with solution delivered through a nasogastric tube is known as what?
正解：A
解説：
The cleansing of the stomach using a solution delivered through a nasogastric tube is known as gastric lavage, commonly referred to as stomach pumping. This medical procedure is primarily used to remove ingested poisons, an overdose of medication, or other harmful substances from a patient's stomach.
During gastric lavage, a flexible tube is inserted through the nose, down the esophagus, and into the stomach. Once the tube is correctly positioned, a saline solution or water is funneled into the stomach. This solution mixes with the stomach contents and is then removed by suction through the same tube. The process may be repeated several times until the effluent (the liquid removed from the stomach) is clear, indicating that the stomach has been thoroughly cleansed.
Gastric lavage must be performed soon after the ingestion of the toxic substance, typically within a few hours, as its effectiveness decreases significantly once the substance has moved beyond the stomach into the intestines. The procedure is only carried out when the benefits outweigh the potential risks, such as aspiration, esophageal perforations, or electrolyte imbalances.
It is crucial for this procedure to be performed by medical professionals in a controlled environment, such as a hospital, where the patient's vital signs can be continuously monitored, and immediate care can be provided in case of complications. Gastric lavage is not suitable for all cases of poisoning or overdose and should only be considered when specifically recommended by healthcare professionals.

A 76-year-old African-American female patient presents with complaints of dyspnea, fatigue, cough, and dependent edema that has been worsening over the past few days. In planning treatment, the ACNS considers:
正解：A
解説：
A 76-year-old African-American female patient presents with symptoms of dyspnea (shortness of breath), fatigue, cough, and dependent edema. These symptoms are concerning and could potentially indicate a serious underlying condition such as heart failure or pulmonary edema. Dyspnea and fatigue may suggest reduced cardiac output, while cough and edema (swelling, typically in the lower limbs due to fluid accumulation) can be associated with fluid congestion, a common feature in heart failure.
Given the severity and the nature of her symptoms, especially in an elderly patient, it is critical to accurately diagnose and manage the underlying cause promptly. The initial step recommended is a referral for hospitalization for evaluation of heart function. This decision is based on the need for a thorough assessment which typically includes diagnostic tests such as echocardiography, electrocardiograms, and possibly cardiac biomarkers. These tests help in confirming the diagnosis, assessing the severity of the condition, and planning appropriate management.
In the hospital, the patient can be monitored closely for any signs of worsening heart function, and immediate interventions can be applied if necessary. Treatment might include diuretics to manage fluid overload, as well as other medications to support heart function depending on the specific findings related to the cause of the heart failure.
The prescription of furosemide (Lasix) 40 mg PO once daily might seem a reasonable option to manage symptoms by reducing fluid overload. However, merely prescribing a diuretic without a comprehensive evaluation risks insufficient treatment and potential complications due to underlying untreated heart conditions. Therefore, while furosemide is part of the management for heart failure, initiating it should ideally occur after a hospital-based evaluation.
Other options such as the addition of a calcium channel blocker or streptokinase therapy are not suitable in this scenario. Calcium channel blockers are generally not beneficial in the treatment of heart failure and can sometimes worsen the condition depending on the type and stage of heart failure. Streptokinase, a thrombolytic agent, is used to dissolve clots typically in the setting of a myocardial infarction (heart attack) and not in heart failure unless a heart attack is suspected as the underlying cause.
In conclusion, the recommendation for hospitalization for evaluation of heart function is the most appropriate and safe approach given the patient's symptoms and potential risks. This approach allows for comprehensive assessment and tailored treatment, which are crucial in managing elderly patients with possible acute heart conditions.
質問 # 190
The Adult Clinical Nurse Specialist is working in a primary care clinic and sees a 28-year old patient with a "pimple" on her left eyelid. Upon examination, the ACNS finds that a 2-mm pustule on the lateral boarder of the left eyelid margin. What is this most consistent with?
正解：B
解説：
The correct diagnosis for a 28-year old patient with a "pimple" on her left eyelid, which presents as a 2-mm pustule on the lateral border of the eyelid margin, is most consistent with a hordeolum, commonly referred to as a stye. A hordeolum is an acute, localized infection or inflammation of the sebaceous glands or hair follicles of the eyelid. The primary causative agent is typically Staphylococcus aureus, a type of bacteria. This condition results in a painful, red, and swollen area on the eyelid, which may look similar to a pimple.
Choice A, a chalazion, differs from a hordeolum in several ways. A chalazion represents a chronic granulomatous inflammation of a meibomian gland (a type of sebaceous gland in the eyelid), leading to a painless, firm, and nontender nodule. It develops more internally within the eyelid rather than at the margin. Unlike a hordeolum, a chalazion is not primarily caused by an acute bacterial infection and tends to be less painful.
Choice C, blepharitis, is a chronic inflammation of the eyelid margin that involves the hair follicles and glands. It is characterized by scaling, redness, and itching of the eyelid margins, and does not present as a localized pustule or "pimple" like formation. Blepharitis tends to have a more prolonged course and requires different management compared to a hordeolum.
Lastly, choice D, acute cellulitis, refers to a diffuse, acute infection of the skin and subcutaneous tissues typically accompanied by signs of systemic infection such as fever. When it affects the eyelids, it often presents with more generalized eyelid swelling, redness, and pain, significantly more extensive than the localized presentation of a hordeolum.
In summary, the description of a 2-mm pustule at the eyelid margin in a young adult aligns best with a hordeolum, due to its characteristic appearance and underlying pathophysiology involving a localized bacterial infection of the eyelid's hair follicles.
質問 # 191
Which of the following is accurate of the respiratory status of a patient in the compensatory stage of shock?
正解：D
解説：
Shock is a critical condition that represents a state of diminished tissue perfusion, leading to inadequate delivery of oxygen and nutrients that are necessary for cellular function. When the body enters shock, it triggers various compensatory mechanisms to maintain homeostasis and vital organ function. There are different stages of shock: initial, compensatory, progressive, and refractory. The compensatory stage of shock is particularly important because the body is actively attempting to correct the imbalance.
During the compensatory stage of shock, several physiological responses occur. The primary goal is to preserve blood flow to vital organs like the heart and brain. To achieve this, the body makes adjustments that can be observed in various vital signs and symptoms: 1. **Blood Pressure:** Initially, blood pressure may remain within normal limits despite the underlying circulatory problems, thanks to the body's compensatory mechanisms such as vasoconstriction and increased heart rate. 2. **Heart Rate:** Typically, there is an increase in heart rate (tachycardia), often exceeding 100 beats per minute. This reaction is driven by the sympathetic nervous system as an attempt to increase cardiac output and improve tissue perfusion. 3. **Respiratory Rate:** To compensate for reduced tissue perfusion and the resulting decrease in oxygen delivery, the respiratory rate increases. A respiratory rate greater than 20 breaths per minute (tachypnea) is commonly observed. This helps to increase oxygen intake and carbon dioxide expulsion, and may also assist in correcting potential acid-base imbalances by blowing off carbon dioxide (thus countering acidosis). 4. **Skin:** The skin might appear cold and clammy due to peripheral vasoconstriction, a compensatory response aimed at shunting blood from the skin and extremities to central organs. 5. **Urinary Output:** There is often a decrease in urinary output because of reduced blood flow to the kidneys. This is part of the body's attempt to conserve fluids and maintain blood volume. 6. **Mental State:** Patients may experience changes in mental status, including confusion or agitation, due to decreased cerebral perfusion or hypoxia. 7. **Acid-Base Balance:** The body may initially experience respiratory alkalosis, where there is an increase in breathing rate and depth, leading to excessive exhalation of CO2.
In summary, when considering the respiratory status of a patient in the compensatory stage of shock, an increased respiratory rate of greater than 20 breaths per minute is a typical finding. This response is a natural reflex to enhance oxygenation and to manage the acid-base balance in the face of decreased tissue perfusion. Recognizing these signs early is crucial for effective management and intervention in shock.
質問 # 192
Which of the medications listed below could potentially exacerbate CHF in a susceptible individual?
正解：C
解説：
The question asks which medication might worsen congestive heart failure (CHF) in a susceptible individual. To answer this, we need to understand the impact of each listed drug on heart function, particularly in the context of CHF.
Furosemide is a loop diuretic commonly used in the treatment of CHF. It works by helping the kidneys eliminate unneeded water and salt from the body through urine. This reduces the volume of fluid circulating through the blood vessels, decreasing the load on the heart. Therefore, furosemide is generally beneficial for CHF patients as it helps alleviate symptoms such as swelling and shortness of breath, rather than exacerbating CHF.
Metoprolol is a beta-blocker that is used to manage several cardiovascular conditions, including CHF. It works by blocking beta-adrenergic receptors in the heart, which slows down the heart rate and reduces the force of the heart muscle's contractions. Initially, it was thought that beta-blockers were not safe for CHF patients due to their effect on reducing cardiac output. However, long-term use has been shown to improve the function of the heart and increase survival rates in CHF patients. Short-term effects, though, might include a decrease in cardiac output, which can be problematic in CHF patients who are unstable or in acute distress.
Metformin is primarily a medication for type 2 diabetes, not directly affecting heart function or cardiac output. It is generally considered safe in patients with CHF unless there are complicating factors such as kidney dysfunction, which is a contraindication due to the risk of lactic acidosis.
Acetaminophen, commonly used for pain and fever, has no direct impact on cardiac output or heart function. It is considered safe in recommended doses for patients with CHF as it does not exacerbate heart failure symptoms.
From the medications listed, while metoprolol might initially pose some risk due to its effect on cardiac output, it is generally beneficial in long-term CHF management. The other medications, furosemide, metformin, and acetaminophen, do not typically exacerbate CHF. In fact, furosemide is often part of the therapeutic regimen for managing CHF symptoms. Therefore, the correct answer depends significantly on the specific circumstances and stability of the CHF patient when considering metoprolol. For a patient in acute CHF distress or not yet stabilized on chronic CHF therapy, metoprolol could potentially exacerbate the condition temporarily.
