A patient with COPD is admitted with shortness of breath and a productive cough. Which of the following interventions should the nurse implement first?

Correct Answer: C

Rationale: Placing the patient in a high-Fowler's position should be implemented first. This intervention helps improve lung expansion, making it easier for the patient to breathe. Elevating the head of the bed reduces the work of breathing and can alleviate symptoms of respiratory distress. Administering oxygen, encouraging coughing and deep breathing, and administering a bronchodilator are important interventions in the care of a patient with COPD, but positioning the patient for optimal lung expansion takes precedence in this scenario.

Correct Answer: D

Rationale: The correct answer is D. Increased urinary output is the desired outcome when administering furosemide to a client with heart failure. Furosemide is a diuretic that promotes the excretion of excess fluids from the body, which helps in reducing fluid overload, a common symptom of heart failure. Choices A, B, and C are not directly related to the action of furosemide in treating heart failure. Visual acuity improvement, decreased respiratory rate, and rapid weight loss are not typical indicators of furosemide effectiveness in managing heart failure.

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: 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: B

Rationale: The correct answer is B: Decreased anginal pain. Verapamil is a calcium channel blocker used to relieve angina by reducing myocardial oxygen demand. Monitoring for decreased anginal pain is essential as it indicates a therapeutic response to the medication. Choices A, C, and D are incorrect as verapamil's primary goal in this context is not to decrease blood pressure, heart rate, or anxiety.
