Correct Answer: B

Rationale: The correct answer is B. Nitroglycerin tablets should be stored in a cool, dark place to maintain their potency. Storing them correctly ensures that they remain effective when needed. Choices A, C, and D are incorrect. Taking one tablet every hour is not the correct dosing regimen for nitroglycerin. Nitroglycerin is usually taken as needed at the onset of chest pain, with specific instructions from the healthcare provider. Taking nitroglycerin with food or antacids is not necessary, as it is usually placed under the tongue for rapid absorption.

Correct Answer: B

Rationale: The client's Glasgow Coma Score is 7. This is calculated by assigning 2 points for eye-opening to pain, 2 points for incomprehensible sounds, and 3 points for flexion posturing. Choices A, C, and D are incorrect. Choice A (4) would be the score if the client displayed decerebrate posturing instead of flexion posturing. Choice C (9) would be the score if the client exhibited eye-opening to speech, confused speech, and decorticate posturing. Choice D (10) would be the score if the client showed eye-opening spontaneously, oriented speech, and obeyed commands, which is not the case here.

Correct Answer: A

Rationale: The correct answer is to monitor for withdrawal symptoms. This is a priority because individuals with a history of substance abuse are at risk of experiencing withdrawal symptoms when the substance is no longer used. Monitoring for withdrawal symptoms is crucial to ensure the client's safety and to manage any potential complications related to substance withdrawal. Encouraging social activities, scheduling regular follow-ups, and providing educational materials are also important aspects of care, but they are not as critical as monitoring for withdrawal symptoms in this immediate scenario.

Correct Answer: A

Rationale: Corrected Rationale: Metformin should be taken with food to minimize gastrointestinal side effects. Choice A is the correct answer as taking metformin with meals can help reduce the likelihood of experiencing gastrointestinal side effects like diarrhea and nausea, which are common side effects of metformin. Choice B is incorrect because metformin actually helps lower blood sugar levels and does not cause hyperglycemia. Choice C is incorrect as metformin is usually taken twice or even three times a day, not just once daily. Choice D is incorrect because metformin is an oral medication, not an injectable one.

Correct Answer: C

Rationale: The correct answer is C: Acquired immunity. Acquired immunity occurs when an individual is given a vaccine or immunization to develop antibodies. This type of immunity is specific and develops after exposure to an antigen. Innate immunity (choice A) is the body's natural defense system present at birth. Passive immunity (choice B) is temporary immunity passed from one individual to another. Natural immunity (choice D) refers to immunity that is not gained through medical intervention or deliberate exposure.
