1. What is the preferred electrical intervention for a patient with ventricular tachycardia with a pulse?

• A. Defibrillation
• B. Synchronized cardioversion
• C. Pacing
• D. Medication administration

Correct answer: B

Rationale: Synchronized cardioversion is the preferred electrical intervention for ventricular tachycardia with a pulse. In this scenario, the heart still has an organized rhythm, so synchronized cardioversion is used to deliver a shock at a specific point in the cardiac cycle, aiming to restore a normal rhythm. Defibrillation (Choice A) is used for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (Choice C) may be used for bradycardias or certain types of heart blocks. Medication administration (Choice D) can be considered for stable ventricular tachycardia, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.

2. A patient is receiving discharge instructions for GERD. Which of the following statements by the patient demonstrates an understanding of the teaching?

• A. I should take my medication with orange juice.
• B. Having a bedtime snack will prevent heartburn.
• C. I will lie down after meals.
• D. I will limit activities that require bending at the waist.

Correct answer: D

Rationale: The correct answer is D. Patients with GERD should avoid activities that increase intra-abdominal pressure, such as bending at the waist, as this can lead to reflux. Choice A is incorrect because medications for GERD are usually taken with water, not citrus juices. Choice B is incorrect as having a bedtime snack can worsen GERD symptoms. Choice C is incorrect because lying down after meals can also exacerbate reflux due to the effects of gravity.

3. What is the primary concern for a patient with a CD4 T-cell count below 180 cells/mm³?

• A. Increased risk of severe infection
• B. Increased risk of anemia
• C. Increased risk of bleeding
• D. Increased risk of dehydration

Correct answer: A

Rationale: A CD4 T-cell count below 180 cells/mm³ indicates a severely immunocompromised state, leading to an increased risk of severe infection. In individuals with low CD4 counts, the immune system is significantly weakened, making them more susceptible to opportunistic infections. Anemia (choice B), bleeding (choice C), and dehydration (choice D) are not the primary concerns associated with a low CD4 T-cell count. While these conditions may occur as secondary effects or complications, the primary focus is on preventing and managing severe infections in patients with severely compromised immune systems.

4. What are the common manifestations of compartment syndrome?

• A. Unrelieved pain, pallor, pulselessness
• B. Redness and swelling
• C. Fever and infection
• D. Swelling and redness

Correct answer: A

Rationale: The correct manifestations of compartment syndrome are unrelieved pain, pallor, and pulselessness. These symptoms indicate compromised blood flow and neurovascular compromise, necessitating immediate medical intervention. Redness and swelling (Choice B) are more commonly associated with inflammation or infection rather than compartment syndrome. Fever and infection (Choice C) are not typical manifestations of compartment syndrome. Swelling and redness (Choice D) are general signs that can be seen in various conditions and are not specific to compartment syndrome.

5. What is a characteristic sign of hypokalemia on an ECG?

• A. Flattened T waves
• B. ST elevation
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.
