Correct Answer: B

Rationale: A client with a higher gravida and para count is at greater risk for uterine atony, which can lead to postpartum hemorrhage. The uterus may be less effective at contracting after multiple pregnancies, causing increased vaginal bleeding. Choices A, C, and D are incorrect because delivering a large baby, having a cesarean delivery, or experiencing prolonged labor do not directly correlate with an increased risk of postpartum hemorrhage in a multigravida client as compared to the gravida and para count.

Correct Answer: D

Rationale: The correct answer is D: Administer 15 grams of a fast-acting carbohydrate. The first step in treating hypoglycemia is to quickly raise the client's blood sugar level. Fast-acting carbohydrates like glucose tablets or juice are essential for this purpose. Giving a glucagon injection is typically reserved for severe hypoglycemia when the client is unable to take anything by mouth. Encouraging the client to eat a high-protein snack is not appropriate for immediate treatment of hypoglycemia. Rechecking the blood glucose level in 15 minutes is important after administering the fast-acting carbohydrate to ensure that the blood sugar has returned to a safe level.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

Correct Answer: B

Rationale: The correct answer is B because a whole-body bright red color indicates a severe reaction to the contrast dye and must be addressed immediately. Choices A, C, and D do not indicate a severe complication during an excretory urogram. Choice A is a common side effect of the dye, choice C could be a normal sensation due to the injection, and choice D may indicate nausea which is less severe compared to a whole-body red color reaction.

Correct Answer: D

Rationale: Fowler's position (head elevated at 45-60 degrees) improves oxygenation by expanding the lungs, making it the best position for clients with dyspnea. Supine or prone positions restrict lung expansion, and Trendelenburg position (head down) can exacerbate breathing difficulties by increasing pressure on the lungs and diaphragm.
