Correct Answer: C

Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.

Correct Answer: B

Rationale: The correct action for the nurse to include when assessing the client's gag reflex is to place a tongue blade on the back half of the tongue. This method effectively tests the gag reflex without causing discomfort. Choice A is incorrect because offering small sips of water through a straw does not assess the gag reflex. Choice C is incorrect as using a penlight to observe the back of the oral cavity does not directly assess the gag reflex. Choice D is incorrect since auscultating breath sounds after the client swallows does not evaluate the gag reflex.

Correct Answer: A

Rationale: The correct answer is A. A 16-year-old who is married can legally sign an informed consent form. In this case, being married at 16 may indicate legal emancipation or the ability to consent to medical treatment. Choice B is incorrect because having schizophrenia doesn't automatically imply incapacity to provide informed consent. Choice C is incorrect as an adoptive parent does not have the legal authority to provide consent for medical treatment on behalf of a child without proper documentation. Choice D is incorrect as a 17-year-old mother would generally not have the legal capacity to give consent for her toddler, as parental consent is usually required for minors.

Correct Answer: A

Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.

Correct Answer: A

Rationale: The correct answer is to administer nitroglycerin sublingually. Administering nitroglycerin sublingually is the priority action for a client with chest pain and a history of coronary artery disease. Nitroglycerin helps dilate the coronary arteries, improving blood flow to the heart muscle and providing rapid relief of chest pain. Obtaining a 12-lead ECG, measuring vital signs, and administering oxygen are important actions but should follow the administration of nitroglycerin in the management of chest pain in a client with coronary artery disease.
