Nursing Elites

1. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

• A. Monitor serum calcium levels.
• B. Monitor serum potassium levels.
• C. Monitor serum sodium levels.
• D. Monitor serum magnesium levels.

Correct answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.

2. A nurse educator is conducting a parenting class for new guardians of infants. Which of the following statements made by a participant indicated understanding?

• A. “I will set my water heater at 130°F.”
• B. “Once my baby can sit up, they should be safe in the bathtub.”
• C. “I will place my baby on their stomach to sleep.”
• D. “Once my infant starts to push up, I will remove the mobile from over the crib.”

Correct answer: D

Rationale: The correct answer is D. Removing the mobile when the baby starts to push up prevents choking hazards as infants can reach and grab objects posing a risk of choking. Choice A is unsafe as setting the water heater at 130°F can scald a child. Choice B is incorrect because even when a baby can sit up, they still require close supervision in the bathtub. Choice C is unsafe as current guidelines recommend placing babies on their backs to sleep to reduce the risk of sudden infant death syndrome (SIDS). Therefore, choices A, B, and C are incorrect or unsafe practices for infant care.

3. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?

• A. Assess the client for a gag reflex
• B. Measure the pH of the gastric aspirate
• C. Place the end of the NG tube in water to observe for bubbling
• D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water

Correct answer: B

Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.

4. The client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the healthcare provider monitor closely?

• A. Potassium
• B. Sodium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: Correct! When a client is taking furosemide (Lasix), monitoring potassium levels is crucial due to the potential for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Low potassium levels can predispose the client to cardiac dysrhythmias. Sodium, calcium, and magnesium levels are not typically affected by furosemide to the same extent as potassium, making them less critical to monitor in this scenario.

5. The nurse is caring for a client who was successfully resuscitated from a pulseless dysrhythmia. Which of the following assessments is MOST critical for the nurse to include in the plan of care?

• A. Hourly urine output
• B. White blood cell count
• C. Blood glucose every 4 hours
• D. Temperature every 2 hours

Correct answer: A

Rationale: Monitoring hourly urine output is crucial after successful resuscitation from a pulseless dysrhythmia to assess kidney function and perfusion. The kidneys are particularly vulnerable to injury following cardiac events due to decreased perfusion during the event. Evaluating urine output hourly allows for early detection of renal impairment or inadequate organ perfusion. Option B, monitoring white blood cell count, is not a priority in this situation as it does not directly relate to immediate post-resuscitation care. Option C, checking blood glucose every 4 hours, is important but not as critical as assessing kidney function and perfusion. Option D, measuring temperature every 2 hours, is relevant for monitoring signs of infection or inflammatory response but is not as crucial as assessing kidney function in this scenario.
