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 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: 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: C

Rationale: Contact precautions are necessary when performing postmortem care on a client with MRSA to prevent the spread of infection. Contact precautions involve using barriers like gloves and gowns to limit direct contact with the deceased individual's body fluids and tissues. Airborne precautions are used for pathogens that are transmitted through the air, like tuberculosis. Droplet precautions are for pathogens that are transmitted through respiratory droplets, such as influenza. Compromised host precautions are not a recognized standard precaution type and are not applicable in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Increased breath sounds. When a client with pneumonia is receiving antibiotic therapy, increased breath sounds indicate that the lungs are clearing and the pneumonia is resolving. This improvement in breath sounds suggests that the antibiotics are effectively treating the infection. Choices A, B, and D are incorrect because a decreased white blood cell count, decreased respiratory rate, and increased heart rate are not specific indicators of the effectiveness of antibiotic therapy in treating pneumonia. While these parameters may change in response to treatment, they do not directly reflect the resolution of the pneumonia infection.

Correct Answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Purulent. Purulent drainage is thick, yellow, and indicates the presence of infection. This type of drainage is typically seen in infected wounds. Choice B, Serous drainage, is thin, clear, and watery, which is normal in the initial stages of wound healing. Sanguineous drainage, choice C, is bright red and indicates fresh bleeding. Serosanguineous drainage, choice D, is pale pink to red and is a mixture of blood and serous fluid commonly seen in the early stages of wound healing.

Correct Answer: A

Rationale: The correct action for the nurse to take when a client has a new prescription for wrist restraints is to pad the client's wrists before applying the restraints. This is important to prevent skin breakdown and injury. Tying the restraints to the side rails of the bed (Choice B) is unsafe and can lead to potential harm for the client. Similarly, securing the restraints to the bed frame (Choice C) is not appropriate as it can restrict the client's movement and cause discomfort. Using a quick-release knot to tie the restraints (Choice D) is also incorrect as it may compromise the effectiveness of the restraints in ensuring client safety.

Correct Answer: A

Rationale: The correct approach for the nurse is to ask the client to elaborate on how their friends discourage them. By doing so, the nurse shows empathy, encourages the client to express their feelings, and gains insight into the situation. This open-ended question can help the nurse understand the specific issues the client is facing and work towards finding solutions collaboratively. Choices B, C, and D do not effectively address the client's concerns or encourage further discussion. Choice B is directive and may come off as judgmental, choice C assumes the friends are not supportive without exploring further, and choice D dismisses the client's feelings and the impact of peer influence.
