Correct Answer: A

Rationale: The correct method of administering insulin to a patient with diabetes is to administer it subcutaneously. Insulin is typically injected into the fatty tissue just below the skin, allowing for a slow and consistent absorption into the bloodstream. Administering insulin intramuscularly (Choice B) is not recommended as it can lead to unpredictable absorption rates and potential complications. Administering insulin intravenously (Choice C) is only done in specific medical settings and not for routine diabetes management. Administering insulin orally (Choice D) is ineffective as the stomach acid would break down the insulin before it can be absorbed.

Correct Answer: A

Rationale: The correct answer is A, Methylergonovine. Methylergonovine is contraindicated in clients with preeclampsia due to the risk of hypertension. Misoprostol (choice B), Dinoprostone (choice C), and Oxytocin (choice D) are appropriate medications for managing postpartum hemorrhage and are not contraindicated in clients with preeclampsia.

Correct Answer: D

Rationale: The correct answer is D because sitting quietly for 5 minutes before measuring blood pressure ensures an accurate reading and helps monitor hypertension. Choice A is incorrect as medications for hypertension should be taken as prescribed, not based on symptoms like dizziness. Choice B is not ideal as blood pressure should be checked more frequently, preferably daily. Choice C is incorrect as stopping medication abruptly once blood pressure is normal can lead to rebound hypertension.

Correct Answer: C

Rationale: The correct answer is Hypokalemia (Choice C). Loop diuretics can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is a common concern with loop diuretic therapy and necessitates regular monitoring. Hyperkalemia (Choice A) is not typically associated with loop diuretics but with conditions like renal failure. Hyponatremia (Choice B) is more common with thiazide diuretics. Hypercalcemia (Choice D) is not a typical concern with loop diuretic use.

Correct Answer: C

Rationale: The correct answer is C: 'Avoid crossing your legs when sitting.' After a total hip arthroplasty, it is important for clients to avoid crossing their legs to prevent complications such as dislocation. Crossing the legs can put strain on the new hip joint, increasing the risk of dislocation. Choice A is incorrect as crossing legs can be harmful. Choice B is incorrect as bending at the waist can strain the hip joint, leading to complications. Choice D is incorrect as using a raised toilet seat is recommended after hip surgery to prevent excessive bending at the hip joint.
