1. What is the priority intervention for a patient with unstable angina?
- A. Administer nitroglycerin
- B. Establish IV access
- C. Auscultate heart sounds
- D. Administer aspirin
Correct answer: A
Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with unstable angina as it helps dilate blood vessels, improve blood flow to the heart, relieve chest pain, and prevent further cardiac damage. Establishing IV access (choice B) may be important but is not the priority over administering nitroglycerin in this scenario. Auscultating heart sounds (choice C) and administering aspirin (choice D) are also important aspects of managing unstable angina, but they are not the immediate priority intervention when a patient is experiencing chest pain.
2. 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.
3. What are the expected ECG findings in hypokalemia?
- A. Flattened T waves
- B. Prominent U waves
- C. Elevated ST segments
- D. Wide QRS complex
Correct answer: A
Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.
4. What medication should be administered first for wheezing due to an allergic reaction?
- A. Albuterol via nebulizer
- B. Cromolyn via nebulizer
- C. Methylprednisolone IV
- D. Aminophylline IV
Correct answer: A
Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction because it quickly opens the airways by relaxing the muscles around the airways. Cromolyn (choice B) is used more for prevention rather than immediate relief of symptoms. Methylprednisolone (choice C) and Aminophylline (choice D) are not the first-line treatments for acute wheezing due to an allergic reaction.
5. What should a healthcare provider monitor for in a patient with hypokalemia?
- A. Monitor for muscle weakness
- B. Monitor for bradycardia
- C. Check deep tendon reflexes
- D. Monitor for hyperglycemia
Correct answer: A
Rationale: Corrected Rationale: Muscle weakness is a common symptom of hypokalemia and should be closely monitored in affected patients. Hypokalemia is a condition characterized by low potassium levels in the blood, which can lead to muscle weakness, cramps, and even paralysis. While bradycardia (slow heart rate) can be associated with severe hypokalemia, monitoring for muscle weakness is more specific to the condition. Checking deep tendon reflexes is not typically a primary monitoring parameter for hypokalemia. Monitoring for hyperglycemia is not directly related to hypokalemia, as hypokalemia is primarily associated with potassium levels in the blood.
