Nursing Elites

1. A nurse is caring for a client who has severe preeclampsia and is receiving magnesium sulfate. The nurse should monitor the client for which of the following findings as an indication of magnesium toxicity?

• A. Decreased deep tendon reflexes
• B. Elevated blood pressure
• C. Increased urinary output
• D. Hyperreflexia

Correct answer: A

Rationale: The correct answer is A: Decreased deep tendon reflexes. Magnesium sulfate toxicity can lead to diminished deep tendon reflexes, respiratory depression, and decreased urine output. Diminished deep tendon reflexes are an early sign of magnesium toxicity and indicate the need to discontinue the infusion. Elevated blood pressure (choice B) is not typically associated with magnesium toxicity. Increased urinary output (choice C) is also not a common finding in magnesium toxicity. Hyperreflexia (choice D) is not consistent with the expected findings of magnesium toxicity, which typically causes decreased reflexes.

2. A nurse is assessing a client with pericarditis. Which of the following findings is the priority for the nurse to report?

• A. Paradoxical pulse
• B. Dependent edema
• C. Pericardial friction rub
• D. Substernal chest pain

Correct answer: A

Rationale: A paradoxical pulse is a sign of cardiac tamponade, a life-threatening complication of pericarditis that requires immediate intervention. It results from decreased cardiac output due to increased pressure in the pericardial sac. Reporting this finding promptly allows for timely treatment to prevent further deterioration. Dependent edema and substernal chest pain are common in pericarditis but are not as urgent as a paradoxical pulse. A pericardial friction rub is a classic finding in pericarditis and indicates inflammation but is not as critical as a paradoxical pulse.

3. A nurse is assessing a client for signs of heart failure. Which of the following findings should the nurse monitor?

• A. Decreased heart rate
• B. Peripheral edema
• C. Increased energy levels
• D. Hyperglycemia

Correct answer: B

Rationale: The correct answer is B: Peripheral edema. Peripheral edema, the accumulation of fluid causing swelling in the extremities, is a classic sign of heart failure due to fluid overload. This occurs because the heart's reduced pumping efficiency leads to fluid backup in the circulatory system. Choices A, C, and D are incorrect. Decreased heart rate is not typically associated with heart failure; instead, tachycardia or an increased heart rate may be observed. Increased energy levels are not an expected finding in heart failure, as this condition often causes fatigue and weakness. Hyperglycemia is not a direct sign of heart failure; however, it can be present in individuals with uncontrolled diabetes or as a result of certain treatments, but it is not a specific indicator of heart failure.

4. A nurse is assessing four clients for fluid balance. Which of the following clients is exhibiting manifestations of dehydration?

• A. A client who has a urine specific gravity of 1.010.
• B. A client who has a weight gain of 2.2 kg (2 lb) in 24 hr.
• C. A client who has a hematocrit of 45%.
• D. A client who has a temperature of 39°C (102°F).

Correct answer: D

Rationale: The correct answer is D because an elevated temperature is a common manifestation of dehydration. Choices A, B, and C are not indicative of dehydration. A urine specific gravity of 1.010 is within normal range, weight gain suggests fluid overload, and a hematocrit of 45% is also within normal limits and not specifically related to dehydration.

5. A nurse is teaching a client about the use of a metered-dose inhaler (MDI). Which instruction should the nurse include in the teaching?

• A. Inhale the medication deeply for 3-5 seconds
• B. Exhale forcefully before inhaling
• C. Shake the MDI vigorously before use
• D. Hold the mouthpiece 2.5-5 cm (1-2 in) in front of the mouth

Correct answer: A

Rationale: Corrected Rationale: Inhaling the medication deeply for 3-5 seconds and holding the breath for 10 seconds after inhalation ensures effective medication delivery to the lungs. Choice A is the correct instruction for the use of a metered-dose inhaler (MDI). Choice B, exhaling forcefully before inhaling, is incorrect as it can lead to decreased medication delivery. Choice C, shaking the MDI vigorously before use, is also incorrect as excessive shaking can cause the medication to clump. Choice D, holding the mouthpiece 2.5-5 cm (1-2 in) in front of the mouth, is not recommended as it may lead to improper inhalation technique.
