1. A healthcare professional is monitoring the respiratory status of a client who has just undergone surgery and is wearing a pulse oximeter. Which of the following coexisting problems is cause for the healthcare professional to suspect that the oxygen saturation readings are not entirely accurate?

Correct answer: C

Rationale: Low blood pressure (hypotension), shock, and the use of peripheral vasoconstricting medications can lead to inaccurate pulse oximetry readings due to impaired peripheral perfusion. Hypertension and infection are not typically associated with inaccurate pulse oximetry readings, while the loss of cough reflex does not directly affect oxygen saturation readings.

2. A client is receiving intermittent bolus feedings via a nasogastric tube. In which position should the nurse place the client once the feeding is complete?

Correct answer: B

Rationale: After intermittent bolus feedings through a nasogastric tube, the correct position for the client is to keep the head of the bed flat. This position helps prevent vomiting and aspiration. Placing the client in a supine position (choice A) can increase the risk of aspiration. The left lateral position (choice C) is not typically used after nasogastric tube feedings. Elevating the head of the bed 30 to 45 degrees (choice D) is suitable for continuous tube feedings to reduce the risk of aspiration, but for intermittent bolus feedings, keeping the head of the bed flat is preferred to prevent regurgitation and aspiration.

3. The nurse is caring for five clients on the medical-surgical unit. Which clients would the nurse consider to be at risk for post-renal acute kidney injury (AKI)? (Select all that apply.)

Correct answer: D

Rationale: Post-renal acute kidney injury (AKI) occurs due to urine flow obstruction, which can result from conditions such as prostate cancer, blood clots in the urinary tract, and ureterolithiasis (kidney stones). Severe burns would lead to pre-renal AKI by reducing blood flow to the kidneys. Lupus would cause intrarenal AKI by affecting the kidney tissue directly. Therefore, options A, B, and C are correct choices for clients at risk for post-renal AKI, making option D the correct answer.

4. The nurse assumes care for a patient who is currently receiving a dose of intravenous vancomycin (Vancocin) infusing at 20 mg/min. The nurse notes red blotches on the patient’s face, neck, and chest and assesses a blood pressure of 80/55 mm Hg. Which action will the nurse take?

Correct answer: B

Rationale: When vancomycin is infused too rapidly, “red man” syndrome may occur; the rate should be 10 mg/min to prevent this. This is a toxic reaction, not an allergic one, so epinephrine is not indicated. Stevens-Johnson syndrome is characterized by a rash and fever. Red man syndrome is not related to renal function.

5. An elderly client is admitted with a diagnosis of bacterial pneumonia. The nurse's assessment of the client will most likely reveal which sign/symptom?

Correct answer: D

Rationale: The onset of pneumonia in the elderly may be signaled by general deterioration, confusion, increased heart rate or increased respiratory rate due to the decreased oxygen- carbon dioxide exchange at the alveoli, known as the V-Q mismatch.
