A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

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: Elevating the head of the bed reduces pressure on bony prominences, which helps prevent pressure ulcers.

Correct Answer: B

Rationale: A positive antinuclear antibody (ANA) titer is a significant finding in clients with systemic lupus erythematosus (SLE) as it indicates active disease. This result should be reported to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and not specifically indicative of disease activity in SLE. Therefore, they do not require immediate reporting to the provider.

Correct Answer: A

Rationale: The correct answer is A: Potassium 3.5 mEq/L. Digoxin can cause hypokalemia as an adverse effect. Monitoring potassium levels is crucial because low potassium levels can increase the risk of digoxin toxicity. Choices B, C, and D are incorrect as they are not directly associated with potential adverse effects of digoxin. Sodium levels are not typically affected by digoxin, calcium levels are not a primary concern with digoxin therapy, and magnesium levels are not the most important to monitor for digoxin adverse effects.

Correct Answer: B

Rationale: The correct answer is B. It is crucial for clients to complete the entire course of antibiotics as prescribed, even if symptoms improve. This helps to ensure that the infection is fully treated and reduces the risk of developing antibiotic resistance. Choice A is incorrect because stopping the medication when symptoms disappear can lead to incomplete treatment. Choice C is incorrect as amoxicillin can be taken with or without food. Choice D is incorrect because taking amoxicillin with milk can decrease its absorption.

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: A

Rationale: The correct answer is A. Clients prescribed lithium need regular monitoring of blood levels to ensure the medication's effectiveness and safety. This monitoring helps to keep the medication within the therapeutic range and prevent toxicity. Choice B is incorrect because lithium is usually taken with food to minimize gastrointestinal side effects. Choice C is not directly related to lithium therapy; however, excessive sodium intake can affect lithium levels. Choice D is incorrect as abruptly stopping lithium can lead to adverse effects and should only be done under healthcare provider guidance.

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: C

Rationale: The correct answer is lean beef because it is a good source of protein and essential nutrients. When providing dietary recommendations to clients with hypertension, it is important to focus on lean protein sources to promote a balanced diet. Bananas, although a healthy fruit, may not be the best choice due to their high potassium content, which can sometimes be a concern for individuals with hypertension. Whole grains are generally a good choice, but lean protein like beef is more suitable in this scenario. Canned soup often contains high levels of sodium, which is not recommended for individuals with hypertension.
