Correct Answer: B

Rationale: To calculate the volume to administer, use the formula: (Volume to administer = (Ordered Dose × Volume on hand) / Dose on hand). In this case, it would be (4 mg × 1 mL) / 5 mg = 0.8 mL. Therefore, the nurse should administer 0.8 mL of diazepam. Choice A (0.2 mL) is incorrect because it miscalculates the dosage. Choice C (1.25 mL) and Choice D (2.0 mL) are incorrect as they do not align with the correct calculation based on the ordered dose and available concentration. The correct answer, 0.8 mL, is derived from accurate dosage calculation and aligns with the formula for IV medication administration, ensuring the safe and effective delivery of the medication to the client.

Correct Answer: B

Rationale: When changing the route of administration from PO to IV, the absorption process is bypassed, leading to a more rapid onset of action of the medication and consequently a quicker effect. Choices A, C, and D are incorrect. Increased drug tolerance and higher doses are not typical outcomes of changing the route of administration. Protein binding does not increase with a change to IV administration; rather, it is the bioavailability and onset of action that are affected. Moreover, an increased therapeutic index reduces the risk of drug toxicity, contrary to what is stated in choice D.

Correct Answer: A

Rationale: When the nurse rolls contaminated gloves inside-out, they are manipulating the mode of transmission in the chain of infection. The gloves, which are contaminated, act as a vehicle for transferring pathogens from the reservoir's portal of exit to a potential portal of entry. Choices B, C, and D are incorrect because the action of rolling contaminated gloves does not directly relate to the portal of entry, reservoir, or portal of exit in the chain of infection.

Correct Answer: D

Rationale: The correct answer is to teach the importance of personal hygiene during menstruation to the client. While respecting the client's beliefs, it is essential to provide education on maintaining hygiene during menstruation. This empowers the client with knowledge to make informed decisions. Options A and B can be considered after providing education. Option C, obtaining brochures, is not the priority as direct communication and teaching would be more effective in addressing the client's concerns.

Correct Answer: C

Rationale: The correct answer is 'Cranberry juice stops pathogens' adherence to the bladder.' Cranberry juice maintains urinary tract health by reducing the adherence of Escherichia coli bacteria to cells within the bladder. This helps prevent UTIs. Options A, B, and D are incorrect because orange juice with vitamin C, apple juice for urine acidification, and grapefruit juice for antibiotic absorption do not have the same proven effectiveness in preventing UTIs as cranberry juice does.
