Correct Answer: B

Rationale: The correct answer is B: History of gastroesophageal reflux disease. Gastroesophageal reflux disease increases the risk of aspiration due to the potential for regurgitation of stomach contents into the esophagus and airways. Choices A, C, and D are not directly related to an increased risk of aspiration. A residual of 65mL 1 hour postprandial may indicate delayed gastric emptying but is not a direct risk factor for aspiration. Receiving a high-osmolarity formula or receiving a feeding in a supine position are not specific risk factors for aspiration unless they contribute to reflux or other related issues.

Correct Answer: B

Rationale: Administering a PRN dose of morphine is the most appropriate action to manage postoperative pain in a client following a colon resection. Morphine is a potent analgesic commonly used to relieve moderate to severe pain, especially in postoperative settings. While assisting the client to change positions in bed, encouraging relaxation techniques, and offering a back massage can provide comfort and support, they may not be sufficient in managing the pain following a major surgical procedure like a colon resection. Therefore, the priority intervention for acute postoperative pain control in this scenario is to administer medication like morphine.

Correct Answer: C

Rationale: The correct answer is C. Clients with hypertension should avoid salt substitutes because they often contain potassium, which can raise potassium levels. Choice A is incorrect as decreasing potassium intake is not necessary unless advised by a healthcare provider. Choice B is incorrect as not all clients with hypertension need to take medication for life. Choice D is incorrect as grapefruit juice does not significantly impact hypertension management.

Correct Answer: D

Rationale: In the advanced stage of ALS, clients often experience swallowing difficulties, known as dysphagia. A speech-language pathologist specializes in assessing and managing these swallowing problems, making them the nurse's priority referral in this case. A psychologist primarily focuses on mental health and emotional well-being, which may not be the most critical issue at this stage. Social workers assist with social support and resources, while occupational therapists help with activities of daily living and mobility, which are important but not the priority when dysphagia is a concern.

Correct Answer: B

Rationale: Thrombophlebitis is a contraindication for the use of combination oral contraceptives due to the increased risk of thromboembolic events such as deep vein thrombosis and pulmonary embolism. Hyperthyroidism, diverticulosis, and hypocalcemia are not typically contraindications for using combination oral contraceptives, making choices A, C, and D incorrect.
