A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?

Correct Answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

Correct Answer: B

Rationale: The correct answer is B. Washing and rinsing the lens storage case daily is essential to prevent contamination and infections. Choice A is incorrect as tap water should not be used to clean soft lenses due to the risk of introducing harmful microorganisms. Choice C is incorrect as the storage solution should not be reused for longer than recommended to maintain its effectiveness and prevent eye infections. Choice D is incorrect because lenses should be stored in a clean, disinfected case, not just in a cool, dry place, to avoid contamination.

Correct Answer: B

Rationale: The appropriate nursing response in this situation is to acknowledge and address the client's concerns empathetically. By expressing understanding and asking if the client is worried about being seen without their teeth, the nurse shows empathy and attempts to alleviate the client's anxiety. Choice A is incorrect as it dismisses the client's feelings. Choice C is inappropriate as it does not directly address the client's agitation. Choice D is not the best response as it minimizes the client's feelings and does not provide emotional support.

Correct Answer: A

Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This step helps prevent obstruction in the tubing, maintaining proper urine flow and reducing the risk of infection. Changing the catheter every 72 hours is not recommended unless clinically indicated, as routine changes can increase the risk of introducing pathogens. Cleaning the perineal area with an antiseptic solution is essential for general hygiene but does not directly prevent catheter-related infections. Irrigating the catheter with normal saline every shift is not a standard practice and can introduce microorganisms into the urinary tract, increasing the risk of infection.

Correct Answer: C

Rationale: The correct answer is C, 'Proximate cause.' Proximate cause establishes the link between the harm suffered and the negligent actions performed by the nurse. In a malpractice lawsuit, proving proximate cause is essential to demonstrate that the nurse's actions directly led to the harm experienced by the client. Choice A, 'Evidence,' is incorrect as evidence is the information presented to support or refute a claim, not specifically the link between harm and negligence. Choice B, 'Tort discovery,' is incorrect as it does not specifically refer to establishing the link between harm and negligence. Choice D, 'Common cause,' is incorrect as it does not capture the legal concept of proximate cause in establishing liability in malpractice cases.

Correct Answer: A

Rationale: Checking the client's pupillary reaction to light is a key assessment to evaluate the oculomotor nerve function. The oculomotor nerve controls the pupil's constriction response to light. Choices B, C, and D are incorrect because testing vision with a Snellen chart, identifying scents, or touching the cornea are not specific assessments for oculomotor nerve function.

Correct Answer: A

Rationale: The correct action is to commend the client for selecting a high biological value protein, as scrambled eggs provide a good protein source for clients with chronic renal failure. Protein is essential for maintaining muscle mass and overall health in these clients. Reminding the client to avoid protein is incorrect as it may lead to protein-energy malnutrition, which is a common concern in chronic renal failure. Suggesting orange juice for absorption is not relevant to the situation, as protein absorption is not a primary concern in this context. Encouraging the client to attend classes on dietary management of chronic renal failure is important for overall education but is not the immediate action needed in response to the client's breakfast choice.

Correct Answer: D

Rationale: The correct answer is to include the type of transmission-based precautions in the report. This information is crucial for infection control when caring for a client with shingles, as it helps prevent the spread of the virus to other clients and healthcare workers. Choices A, B, and C are not directly related to managing a client with shingles. Option A about the location of breakfast is irrelevant to the client's condition. Option B about vital sign measurements, though important, is not the priority when discussing a client with shingles. Option C mentions 'specific times the client had visitors,' which is not as crucial as knowing the specific precautions in place to prevent transmission of the virus.

Correct Answer: A

Rationale: The correct way to prevent self-injury when lifting a bedside cabinet is by standing close to the cabinet. By standing close, the individual can maintain better control and balance while lifting, reducing the risk of injury. Bending at the waist when lifting (choice B) can strain the back and lead to injury. Twisting while lifting (choice C) can also cause strain and imbalance. Lifting with a quick motion (choice D) can increase the risk of injury due to lack of control and improper body mechanics.
