Nursing Elites

1. A patient receives 3% NaCl solution for correction of hyponatremia. Which assessment is most important for the nurse to monitor while the patient is receiving this infusion?

• A. Lung sounds
• B. Urinary output
• C. Peripheral pulses
• D. Peripheral edema

Correct answer: A

Rationale: The correct answer is A: Lung sounds. Hypertonic solutions like 3% NaCl can cause water retention, leading to fluid excess. Monitoring lung sounds is crucial as crackles may indicate pulmonary edema, a serious manifestation of fluid excess. While monitoring urinary output, peripheral pulses, and peripheral edema are also important when administering hypertonic solutions, they do not provide immediate clues to acute respiratory or cardiac decompensation like lung sounds.

2. A patient is admitted for hypovolemia associated with multiple draining wounds. Which assessment would be the most accurate way for the nurse to evaluate fluid balance?

• A. Skin turgor
• B. Daily weight
• C. Presence of edema
• D. Hourly urine output

Correct answer: B

Rationale: Daily weight is the most easily obtained and accurate means of assessing volume status. Skin turgor varies considerably with age and can be affected by various factors other than fluid balance. Presence of edema indicates excess fluid has moved into the interstitial space, which may not always be directly correlated with overall fluid balance. Hourly urine outputs, though important, do not provide a comprehensive picture of fluid balance as they do not consider fluid intake, insensible losses, or other sources of fluid loss.

3. A patient is admitted to the emergency department with severe fatigue and confusion. Laboratory studies are done. Which laboratory value will require the most immediate action by the nurse?

• A. Arterial blood pH is 7.32.
• B. Serum calcium is 18 mg/dL.
• C. Serum potassium is 5.1 mEq/L
• D. Arterial oxygen saturation is 91%.

Correct answer: B

Rationale: The correct answer is B. A serum calcium level of 18 mg/dL is significantly elevated, posing a high risk for cardiac dysrhythmias. Immediate action is required to initiate cardiac monitoring and notify the healthcare provider. While the abnormalities in arterial blood pH, serum potassium, and arterial oxygen saturation also need attention, they are not as immediately life-threatening as the critically high serum calcium level. Therefore, addressing the serum calcium level takes precedence in this scenario.

4. The nurse assesses a client who has a nasal cannula delivering oxygen at 2 L/min. To assess for skin damage related to the cannula, which areas should the nurse observe? (Select all that apply).

• A. Tops of the ears
• B. Bridge of the nose
• C. Around the nostrils
• D. Over the cheeks

Correct answer: C

Rationale: The correct answer is C: 'Around the nostrils.' Constant pressure from the tubing may create skin damage to the areas of skin and bony prominences the nasal cannula will be resting on, including around the nostrils. Choice A, 'Tops of the ears,' is incorrect as the cannula does not rest on the ears. Choice B, 'Bridge of the nose,' is incorrect because the cannula typically rests under the nose. Choice D, 'Over the cheeks,' is also incorrect as the cannula does not typically rest on the cheeks.

5. A patient with renal failure has been taking aluminum hydroxide/magnesium hydroxide suspension (Maalox) at home for indigestion. The patient arrives for outpatient hemodialysis and is unresponsive to questions and has decreased deep tendon reflexes. Which action should the dialysis nurse take first?

• A. Notify the patient’s health care provider.
• B. Obtain an order to draw a potassium level.
• C. Review the magnesium level on the patient’s chart.
• D. Teach the patient about the risk of magnesium-containing antacids

Correct answer: A

Rationale: The health care provider should be notified immediately. The patient has a history and manifestations consistent with hypermagnesemia. The nurse should check the chart for a recent serum magnesium level and make sure that blood is sent to the laboratory for immediate electrolyte and chemistry determinations. Dialysis should correct the high magnesium levels. The patient needs teaching about the risks of taking magnesium-containing antacids. Monitoring of potassium levels also is important for patients with renal failure, but the patient’s current symptoms are not consistent with hyperkalemia.
