Correct Answer: A

Rationale: The symptoms described, including bloodshot eyes, a voracious appetite, and dry mouth, are consistent with marijuana use. Bloodshot eyes are a common side effect of marijuana due to its effect on blood vessels in the eyes. Marijuana also often causes an increase in appetite (known as 'the munchies') and can result in dry mouth. Amphetamines typically cause symptoms like increased alertness, energy, and decreased appetite. Barbiturates and anxiolytics would not typically cause bloodshot eyes, a voracious appetite, and dry mouth as described in the scenario. Therefore, the most likely drug abuse the nurse would suspect in this case is marijuana.

Correct Answer: B

Rationale: The correct answer is B: Canned soup. Canned soup is commonly high in sodium content, which is not suitable for a patient on a low-sodium diet. Fresh fruit, whole grain bread, and grilled chicken typically have lower sodium levels and can be included in a low-sodium diet. Therefore, the patient should avoid canned soup to adhere to the requirements of a low-sodium diet.

Correct Answer: B

Rationale: Garlic is the correct answer. It is high in prebiotics, which are non-digestible fibers that promote the growth of beneficial gut bacteria. Chicken, white rice, and cheese are not significant sources of prebiotics. Chicken is a good source of protein, white rice is a carbohydrate, and cheese is a dairy product, none of which are high in prebiotics.

Correct Answer: B

Rationale: The Z-Track technique is aimed at preventing medication leakage into the surrounding tissues by sealing the medication in the muscle, not by creating a Zig-Zag pattern. Choice A is correct as Z-Track injections help prevent irritation. Choice C is correct as it accurately describes how the technique works. Choice D is also correct as the Z-Track technique is commonly used when administering Parenteral Iron to prevent staining and irritation of the surrounding tissues.

Correct Answer: C

Rationale: The correct answer is C. Ham is high in vitamin K, which can interfere with warfarin. Vitamin K can decrease the effectiveness of warfarin, an anticoagulant medication. Choices A, B, and D do not contain high levels of vitamin K and are less likely to interfere with the client's warfarin therapy.
