Nursing Elites

1. Which of the following is a sign of hypocalcemia?

• A. Hyperactive reflexes.
• B. Depressed reflexes.
• C. Muscle cramps.
• D. Seizures.

Correct answer: A

Rationale: Hyperactive reflexes are a classic sign of hypocalcemia. Hypocalcemia leads to increased neuromuscular excitability, resulting in hyperactive reflexes. Depressed reflexes (Choice B) are not typically associated with hypocalcemia. Muscle cramps (Choice C) can be seen in hypocalcemia due to muscle irritability but are not a specific sign. Seizures (Choice D) can occur in severe cases of hypocalcemia but are not as common as hyperactive reflexes.

2. A female patient who is allergic to penicillin will begin taking an antibiotic to treat a lower respiratory tract infection. The patient tells the nurse that she almost always develops a vaginal yeast infection when she takes antibiotics and that she will take fluconazole (Diflucan) with the antibiotic being prescribed. Which macrolide should the nurse question for this patient?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Erythromycin (E-Mycin)
• D. Fidaxomicin (Dificid)

Correct answer: C

Rationale: The nurse should question the prescription of erythromycin for this patient. When erythromycin is given concurrently with fluconazole, erythromycin blood concentration and the risk of sudden cardiac death increase. Therefore, it is not recommended to use erythromycin in combination with fluconazole for this patient. Azithromycin, clarithromycin, and fidaxomicin are alternative macrolide antibiotics that can be considered for this patient without the same risk of interactions when used with fluconazole.

3. The client with chronic renal failure is receiving hemodialysis. Which of the following laboratory values should the nurse monitor closely?

• A. Hemoglobin level.
• B. Blood urea nitrogen (BUN) level.
• C. Serum potassium level.
• D. Creatinine level.

Correct answer: C

Rationale: The serum potassium level should be monitored closely in clients undergoing hemodialysis due to the risk of hyperkalemia. Hemodialysis is used to remove waste products and excess electrolytes like potassium from the blood. Monitoring potassium levels is crucial because an imbalance can lead to serious cardiac complications, making it the priority value to monitor in this scenario. Monitoring hemoglobin levels (choice A) is important for anemia assessment in chronic renal failure but is not directly related to hemodialysis. Blood urea nitrogen (BUN) levels (choice B) and creatinine levels (choice D) are commonly monitored in renal function tests but are not the top priority for monitoring in a client undergoing hemodialysis.

4. A client who has heart failure is admitted with a serum potassium level of 2.9 mEq/L. Which action is most important for the nurse to implement?

• A. Administer 20 mEq of potassium chloride.
• B. Initiate continuous cardiac monitoring.
• C. Arrange a consultation with the dietitian.
• D. Educate about the side effects of diuretics.

Correct answer: B

Rationale: Hypokalemia, defined as a serum potassium level below the normal range of 3.5 to 5 mEq/L, can lead to changes in myocardial irritability and ECG waveform, potentially causing life-threatening dysrhythmias. Therefore, the priority action for the nurse is to initiate continuous cardiac monitoring to promptly detect any abnormal heart rhythms or ventricular ectopy. This monitoring is crucial for assessing the impact of potassium replacement therapy on the cardiac rhythm and ensuring the safety of the client. While administering potassium chloride is important for correcting the hypokalemia, it should occur after cardiac monitoring is in place. Consulting with a dietitian and educating about diuretic side effects are relevant aspects of care but are not the immediate priority in this situation where cardiac monitoring takes precedence for timely intervention.

5. A client diagnosed with a history of asthma and bronchitis arrives at the clinic with shortness of breath, productive cough with thickened, tenacious mucus, and the inability to walk up a flight of stairs without experiencing breathlessness. Which action is most important for the nurses to instruct the client about self-care?

• A. Call the clinic if undesirable side effects of medications occur
• B. Avoid crowded enclosed areas to reduce pathogen exposure
• C. Increase the daily intake of oral fluids to liquefy secretions
• D. Teach anxiety reduction methods for feelings of suffocation

Correct answer: C

Rationale: Increasing the daily intake of oral fluids is crucial for clients with asthma and bronchitis as it helps to liquefy thickened mucus, making it easier to clear the airways and manage symptoms. This self-care measure can improve the client's ability to breathe more effectively. Choice A is not the most immediate concern when addressing thickened mucus and breathing difficulties. While avoiding crowded areas is beneficial to prevent respiratory infections, it is not directly related to managing thickened secretions. Teaching anxiety reduction methods is important for overall well-being, but it does not directly address the physiological issue of thickened mucus in the airways.
