Correct Answer: D

Rationale: Dry, brittle hair is a common sign of malnutrition, often seen in clients with anorexia nervosa. In anorexia nervosa, the body lacks essential nutrients due to severe calorie restriction, leading to dryness and brittleness of the hair. Choices A, B, and C are less likely to directly indicate anorexia nervosa. Preoccupation with calories can be a behavioral symptom, thick body hair is not a typical finding associated with anorexia nervosa, and a sore tongue is more commonly related to nutritional deficiencies like vitamin deficiencies rather than anorexia nervosa.

Correct Answer: B

Rationale: The correct answer is B: Spinach and beef. Spinach is a good source of non-heme iron, while beef provides heme iron, both essential for treating iron deficiency anemia. Yogurt and mozzarella (choice A) are not significant sources of iron. Fish and cottage cheese (choice C) do not provide as much iron as spinach and beef. Turkey slices and milk (choice D) are also not as rich in iron compared to spinach and beef.

Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is to call the practitioner, report the client's symptoms, and obtain further orders. The client's symptoms, including severe abdominal pain, pallor, perspiration, thready rapid pulse, and feeling faint, are indicative of potential complications like internal bleeding, which require immediate medical evaluation. Explaining to the client that it is too early for pain medication or repositioning the client for comfort are not appropriate actions given the severity of the symptoms. Administering the injection early without consulting the practitioner can be dangerous and may worsen the client's condition.

Correct Answer: D

Rationale: The correct answer is D. A beta blocker should be withheld if the apical pulse is below 60, as it can further decrease the heart rate. Choice A is not a reason to question administering a beta blocker as the blood pressure is within normal range. Choice B is not directly related to the administration of a beta blocker. Choice C may indicate a potential adverse effect of another medication, but it does not specifically warrant questioning the administration of the beta blocker.

Correct Answer: A

Rationale: Establishing rapport with the client is crucial in postoperative care to create a trusting relationship, reduce embarrassment, and enhance comfort during assessments. Encouraging the client to lie in the lithotomy position is not recommended after a hemorrhoidectomy as it can be uncomfortable and may disrupt wound healing. Milking the tube inserted during surgery is not a standard practice and could lead to complications. Digitally dilating the rectal sphincter is not indicated post-hemorrhoidectomy and can cause harm to the client.
