Nursing Elites

1. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which laboratory value is most concerning?

• A. Serum glucose of 300 mg/dL
• B. Blood pressure of 140/90 mmHg
• C. Serum osmolarity of 320 mOsm/kg
• D. Serum pH of 7.30

Correct answer: C

Rationale: In a client with hyperglycemic hyperosmolar syndrome (HHS), a serum osmolarity of 320 mOsm/kg is the most concerning laboratory value. This high osmolarity indicates severe dehydration, which can lead to serious complications. Elevated serum glucose levels (choice A) are expected in HHS but do not directly reflect dehydration. Blood pressure (choice B) and serum pH (choice D) are important parameters to monitor but are not the most concerning values in HHS compared to serum osmolarity.

2. A client with pneumonia has arterial blood gases levels at: pH 7.33; PaCO2 49 mm/Hg; HCO3 25 mEq/L; PaO2 95. What intervention should the nurse implement based on these results?

• A. Institute coughing and deep breathing protocols.
• B. Administer oxygen via nasal cannula.
• C. Prepare for intubation and mechanical ventilation.
• D. Increase IV fluids to improve hydration.

Correct answer: A

Rationale: The ABG results indicate respiratory acidosis due to an elevated PaCO2 (49 mm/Hg), indicating hypoventilation. The appropriate intervention for respiratory acidosis is to improve ventilation. Coughing and deep breathing protocols can help the client to effectively ventilate and improve gas exchange. Administering oxygen via nasal cannula (Choice B) may be necessary in respiratory distress situations, but addressing the underlying cause of hypoventilation is crucial. Intubation and mechanical ventilation (Choice C) are not the first-line interventions for uncomplicated respiratory acidosis. Increasing IV fluids (Choice D) does not directly address the respiratory acidosis present in this scenario.

3. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Blood pressure of 110/70 mmHg

Correct answer: C

Rationale: The correct answer is C. The use of accessory muscles indicates increased work of breathing and may signal respiratory failure in a client with COPD, requiring immediate intervention. Oxygen saturation of 90% is within an acceptable range for COPD patients on supplemental oxygen. A respiratory rate of 24 breaths per minute is slightly elevated but not an immediate concern. A blood pressure of 110/70 mmHg is within the normal range and does not require immediate intervention in this scenario.

4. A client with a history of chronic kidney disease is scheduled for a CT scan with contrast. Which laboratory value should the nurse review before the procedure?

• A. Serum potassium
• B. Blood urea nitrogen (BUN)
• C. Serum creatinine
• D. Serum glucose

Correct answer: C

Rationale: Before a CT scan with contrast, the nurse should review the serum creatinine level. This is crucial in assessing kidney function because contrast agents can potentially worsen renal function, leading to contrast-induced nephropathy. Monitoring serum creatinine helps in identifying patients at risk and taking necessary precautions. Serum potassium (Choice A) is important in conditions like hyperkalemia but is not the priority before a contrast CT scan. Blood urea nitrogen (BUN) (Choice B) is another renal function test but is not as specific as serum creatinine for assessing kidney function. Serum glucose (Choice D) is important in monitoring blood sugar levels, especially in diabetic patients, but it is not directly related to the risk of contrast-induced nephropathy in this scenario.

5. Which needle should the nurse use to administer intravenous fluids (IV) via a client's implanted port?

• A. The one with the clamp and no needle
• B. A butterfly needle
• C. A non-coring (Huber) needle
• D. A standard hypodermic needle

Correct answer: C

Rationale: The correct needle to use for administering intravenous fluids via an implanted port is a non-coring (Huber) needle. This type of needle is specifically designed to access implanted ports without coring the septum, which helps prevent damage. Choice A, the one with the clamp and no needle, is incorrect as it does not describe a needle suitable for accessing an implanted port. Choice B, a butterfly needle, is not typically used for accessing implanted ports. Choice D, a standard hypodermic needle, is not ideal for accessing ports as it can damage the septum.
