Correct Answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.

Correct Answer: A

Rationale: The correct answer is A: Pain Management. After abdominal surgery, one of the primary goals of post-operative care is to manage the patient's pain effectively to ensure their comfort and promote recovery. While wound care, prevention of complications, and ensuring digestive function are also important aspects of post-operative care, pain management takes precedence as it directly impacts the patient's well-being and recovery process.

Correct Answer: A

Rationale: Correct answer: To assess a patient with potential diabetic ketoacidosis (DKA), healthcare providers should monitor blood glucose and check for ketones in the urine. Elevated blood glucose levels and the presence of ketones in urine are indicative of DKA. Choice B is incorrect because administering insulin and providing fluids are treatments for DKA rather than assessment measures. Choice C is incorrect as administering potassium and checking for electrolyte imbalance are interventions related to managing DKA complications, not initial assessment. Choice D is incorrect because administering sodium bicarbonate and monitoring urine output are not primary assessment actions for DKA.

Correct Answer: B

Rationale: The axillary method is the most appropriate for newborns because it is non-invasive and safe. Rectal temperature measurement can be uncomfortable and poses a risk of injury, especially in newborns. Oral temperature measurement is not recommended for newborns due to their inability to cooperate and potential inaccuracies. Tympanic temperature measurement may not be as accurate in newborns compared to older children or adults.

Correct Answer: B

Rationale: The healthcare professional's first action before administering a blood transfusion should be to verify that the client's blood type matches the blood product. This step is crucial to ensure compatibility and prevent potentially severe transfusion reactions. Checking the client's temperature (Choice A) is important but not the first action in this scenario. Administering the blood through an IV push (Choice C) is incorrect as blood transfusions are typically administered as a slow infusion. Ensuring the blood is warmed before administration (Choice D) is not the first action and is not a standard practice in blood transfusions.
