Correct Answer: A

Rationale: The correct answer is A: Decreased sense of taste. As individuals age, they may experience a decrease in their sense of taste due to changes in taste buds and a decrease in saliva production. This can lead to a reduced ability to taste flavors or distinguish between different tastes. Choices B, C, and D are incorrect. Decreased blood pressure is not a consistent physiological change with aging; instead, blood pressure may increase or remain stable. Gastric secretions tend to decrease with age, leading to issues like decreased absorption of certain nutrients. Accommodation to near vision typically decreases with age, causing a condition known as presbyopia, where individuals have difficulty focusing on close objects.

Correct Answer: B

Rationale: Digoxin is commonly prescribed to manage atrial fibrillation by controlling heart rate. While Warfarin is used to prevent blood clots, it is not primarily used for controlling heart rate in atrial fibrillation. Aspirin is not the first-line treatment for atrial fibrillation and is generally not recommended for rhythm control. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure, but it is not typically prescribed as the primary medication for managing atrial fibrillation.

Correct Answer: C

Rationale: The correct answer is C: Teach the client pursed-lip breathing technique. Pursed-lip breathing helps clients with COPD improve oxygenation and reduce shortness of breath. Choice A is incorrect because deep breathing and coughing are not recommended every 4 hours for clients with COPD. Choice B is incorrect because a diet high in carbohydrates and low in protein is not specifically indicated for COPD. Choice D is incorrect because fluid restriction is not a standard intervention for COPD unless the client has comorbid conditions that necessitate it.

Correct Answer: D

Rationale: The correct answer is to determine the pain level first. Assessing the client's pain is crucial before any procedure to ensure their comfort and safety. Applying skin preparation to wound edges (Choice A) may come later in the process after ensuring the client's comfort. Donning sterile gloves (Choice B) is important before directly handling the wound but can follow pain assessment. Normal saline (Choice C) might be used during wound cleansing but is not the initial step in this situation.

Correct Answer: A

Rationale: The correct answer is A. A heart rate of 58/min is indicative of bradycardia, a potential sign of digoxin toxicity, which should be reported immediately. While weight gain, respiratory rate, and temperature are important parameters to monitor, they are not as critical as identifying bradycardia in a client taking digoxin.
