Correct Answer: B

Rationale: The correct answer is B. A weight gain of 1 kg (2.2 lb) in 24 hours is concerning as it indicates fluid retention, which can be a sign of complications in clients receiving chemotherapy. Rapid weight gain can be associated with conditions like fluid overload or electrolyte imbalances, which need prompt medical attention. Choices A, C, and D are not typically immediate concerns related to chemotherapy. Alopecia (choice A) is a common side effect of chemotherapy, a white blood cell count of 6,000/mm³ (choice C) falls within the normal range, and a temperature of 37.2°C (99°F) (choice D) is slightly elevated but not a critical finding in this context.

Correct Answer: C

Rationale: The correct answer is C. A serum creatinine level of 2.8 mg/dL indicates impaired kidney function and should be reported to the healthcare provider. Elevated serum creatinine levels are indicative of decreased kidney function and potential progression of chronic kidney disease. Choices A, B, and D are within normal ranges and do not signify immediate concerns related to kidney disease. Urine output of 80 mL/hr is appropriate, a blood pressure of 140/90 mm Hg is considered prehypertensive but not acutely concerning, and a heart rate of 72/min falls within the normal range.

Correct Answer: A

Rationale: The correct initial nursing action for a patient presenting with chest pain is to administer aspirin. Aspirin helps reduce the risk of further clot formation in patients experiencing chest pain, as it has antiplatelet effects. Repositioning the patient, providing pain relief, or preparing for surgery are not the first-line interventions for chest pain. Repositioning the patient may be necessary to ensure comfort and safety, pain relief can be provided after further assessment and diagnostic tests, and preparing for surgery would only be considered after a thorough evaluation and confirmation of the need for surgical intervention.

Correct Answer: A

Rationale: The correct answer is A: Administer anticoagulants. Administering anticoagulants is crucial in managing patients with suspected DVT as it helps prevent further clot formation and reduces the risk of complications like pulmonary embolism. Choice B, applying compression stockings, is more focused on preventing DVT in high-risk patients rather than managing an established case. Encouraging ambulation, choice C, is beneficial in the prevention of DVT but is not the primary management for suspected cases. Monitoring oxygen saturation, choice D, is important in overall patient care but is not the primary intervention for suspected DVT.

Correct Answer: B

Rationale: The correct answer is B. Walking regularly is beneficial for clients with osteoporosis as it helps maintain bone density and prevent fractures. Choice A is not the most appropriate because clients with osteoporosis often require more than just calcium supplements. Choice C is incorrect as weight-bearing exercises actually help strengthen bones. Choice D is important, but walking regularly has a more direct impact on bone health in clients with osteoporosis.
