Correct Answer: A

Rationale: The correct answer is A: 'Take a tablet every 5 minutes for pain relief, up to three doses.' Nitroglycerin sublingual tablets are used to relieve chest pain or to prevent chest pain before activities known to cause angina. The tablets should be taken every 5 minutes for pain relief, up to three doses, as prescribed. Choice B is incorrect because nitroglycerin sublingual tablets should be placed under the tongue until they dissolve, not taken with water. Choice C is incorrect because nitroglycerin sublingual tablets should not be chewed but placed under the tongue for absorption. Choice D is incorrect because nitroglycerin tablets should be stored in their original container at room temperature away from light and moisture.

Correct Answer: C

Rationale: The correct answer is C: Penicillin allergy. Penicillin allergy is a contraindication for ceftriaxone because both medications are beta-lactam antibiotics. Seizure disorder (choice A), hypertension (choice B), and hyperlipidemia (choice D) are not contraindications for ceftriaxone and do not directly affect the use of this antibiotic.

Correct Answer: C

Rationale: The correct answer is C: Proliferative phase. During the proliferative phase of wound healing, collagen is added to the wound to promote tissue regeneration. In the hemostasis phase (choice A), the primary goal is to stop bleeding by forming a blood clot. The inflammatory phase (choice B) involves cleaning the wound and preparing it for healing. The maturation phase (choice D) is when the wound undergoes remodeling and gains strength, but collagen addition primarily occurs during the proliferative phase.

Correct Answer: D

Rationale: Elevating the client's right arm on a pillow is essential post-mastectomy to reduce swelling and promote circulation. Placing the client in the supine position may not be comfortable or ideal after a mastectomy. Encouraging the client to lift objects with the right arm can strain the surgical site and hinder healing. Measuring the client's blood pressure on the right arm should be avoided to prevent disruption to the area and inaccurate readings.

Correct Answer: B

Rationale: The correct answer is B: "Avoid foods that are high in fat." Clients with IBS should avoid foods high in fat as they can exacerbate symptoms such as abdominal pain, bloating, and diarrhea. High-fiber foods, choice A, can sometimes worsen symptoms in individuals with IBS. Increasing intake of dairy products, choice C, may also worsen symptoms for some individuals with IBS, especially if they are lactose intolerant. Drinking carbonated beverages, choice D, can contribute to bloating and gas, making symptoms worse for individuals with IBS.
