Correct Answer: C

Rationale: The correct answer is monitoring the respiratory rate. Morphine can depress respiratory function, leading to respiratory depression or arrest. Therefore, closely monitoring the client's respiratory rate is crucial to detect any signs of respiratory distress. While blood pressure, heart rate, and temperature are important assessments, in this scenario, respiratory rate takes precedence due to the potential respiratory complications associated with morphine administration.

Correct Answer: C

Rationale: The correct angle for administering a subcutaneous injection, such as insulin, is 90 degrees. This angle allows for the medication to be delivered into the subcutaneous layer of tissue beneath the skin. A 45-degree angle is typically used for administering subcutaneous injections in infants or those with reduced adipose tissue, while a 60-degree angle is commonly used for intramuscular injections. A 30-degree angle is not a standard angle for subcutaneous injections.

Correct Answer: B

Rationale: The correct answer is B. Any drainage from the incision site should be monitored, and any signs of infection, such as increased redness or warmth, need to be reported to the healthcare provider. Choices A, C, and D provide accurate information about signs of infection after surgery and do not indicate a need for further teaching.

Correct Answer: D

Rationale: The correct answer is D, poor impulse control. Right hemisphere strokes commonly affect judgment and safety awareness, leading to poor impulse control. Choices A, B, and C are incorrect for this scenario. Deficits in the right visual field are associated with left hemisphere strokes, while the inability to discriminate words and letters is typically seen with left hemisphere damage. Motor retardation is more common in strokes affecting the motor areas of the brain, not specifically related to right hemisphere strokes.

Correct Answer: C

Rationale: In a postoperative client, decreased urine output is a crucial finding as it can indicate impaired kidney function or inadequate fluid balance. Prioritizing assessment and intervention for decreased urine output is essential to prevent complications like acute kidney injury. Elevated temperature, low blood pressure, and increased heart rate are also important, but they may not be as urgent or directly related to kidney function in a postoperative client.
