Correct Answer: C

Rationale: The correct answer is 'Bradycardia.' Propranolol is a beta-blocking agent used to decrease the heart rate. In the case of bleeding esophageal varices, propranolol is given to reduce the risk of bleeding by keeping the heart rate around 55 beats per minute. Monitoring for bradycardia is essential as the medication's intended effect is to lower the heart rate. Choices A, B, and D are incorrect because propranolol would not typically cause hypertension, hyperkalemia, or arthralgia.

Correct Answer: D

Rationale: The correct answer is 'No action is necessary.' In this scenario, the fetal heart deceleration of uniform shape observed is an early deceleration resulting from head compression. Early decelerations are benign and typically do not require any intervention as they mirror the contraction pattern. It is essential to closely observe both the mother and the baby. Administering O2 (Choice A) is not necessary as early decelerations do not indicate fetal distress. Turning the client on her left side (Choice B) is not required for early decelerations. Notifying the physician (Choice C) is not needed for this type of deceleration, as it is a normal response to head compression during labor.

Correct Answer: C

Rationale: The client taking Antabuse should avoid foods that contain alcohol or vinegar as they can trigger a disulfiram reaction. Pickles and vinaigrette dressing often contain vinegar, which the client should avoid. Beef is safe to consume. Choices A, B, and D do not contain alcohol or vinegar, so they are allowed for the client taking Antabuse.

Correct Answer: B

Rationale: The correct answer is diabetes. In chronic pancreatitis, the pancreas may become unable to produce sufficient insulin, leading to diabetes. This connection underscores the importance of monitoring blood sugar levels and understanding the signs and symptoms of diabetes in clients with chronic pancreatitis. Choice A, hypertension, is not directly associated with pancreatic disease but rather with cardiovascular health. Choice C, hypothyroidism, and Choice D, Graves' disease, are unrelated to pancreatic disease and are endocrine disorders affecting the thyroid gland.

Correct Answer: D

Rationale: Pyridoxine is the correct choice in this scenario because it is used as a prophylaxis to prevent neuritis, a possible nervous system side-effect of isoniazid therapy. Neuritis is a condition that involves inflammation of the nerves and can be a side effect of isoniazid. Pyridoxine, also known as vitamin B6, helps prevent this side effect. Vitamin E (Alpha tocopherol), vitamin C (Ascorbic acid), and vitamin D (Calcitriol) do not specifically address the nervous system side-effects associated with isoniazid therapy, making them incorrect choices.
