Correct Answer: C

Rationale: The correct answer is C: Elevated temperature. A fever may indicate infection, a common and serious complication of chemotherapy, requiring prompt intervention. Choice A, Alopecia, is a common side effect of chemotherapy but not a sign of a complication. Choice B, Weight gain, is not typically a sign of a complication of chemotherapy. Choice D, Decreased hemoglobin level, may occur due to chemotherapy but is not a direct sign of a complication.

Correct Answer: D

Rationale: The correct answer is D, 'Mouth sores.' Mouth sores (stomatitis) are a common and potentially serious side effect of chemotherapy. They can lead to difficulty eating, increased risk of infection, and overall decreased quality of life for the client. While alopecia, fatigue, and nausea/vomiting are also common side effects of chemotherapy, they are generally manageable and do not pose the same level of immediate concern as the development of mouth sores in a client undergoing chemotherapy.

Correct Answer: D

Rationale: The correct answer is D: 'Avoid visiting if you've had a recent infection.' Before a hematopoietic stem cell transplantation, it is essential for visitors to refrain from visiting if they have had a recent illness or vaccination to minimize the risk of infection to the patient. Choice A is incorrect because emphasizing a negative outcome is not beneficial to the patient or their family. Choice B is incorrect as it is not necessary to abstain from food for a hematopoietic stem cell transplantation. Choice C is irrelevant to the situation as wearing a hospital gown is not the key information for family and friends to be aware of.

Correct Answer: D

Rationale: Inspiratory stridor is the correct answer as it suggests airway obstruction, a critical issue requiring immediate intervention. Frequent swallowing (choice A) is a common postoperative finding and does not indicate an immediate need for intervention. The presence of mucous membranes (choice B) is a normal finding and does not require immediate intervention. Bubbling in the water-seal chamber (choice C) of a chest tube drainage system is an expected finding and indicates proper functioning of the system, not an immediate need for intervention.

Correct Answer: A

Rationale: The correct answer is A: Encouraging fluids. In a client with multiple myeloma, encouraging fluids is a priority intervention to prevent kidney damage from high calcium levels. Adequate hydration helps maintain renal function and prevents complications. Providing frequent oral care (Choice B) is essential for clients at risk of mucositis or oral infections, such as those undergoing chemotherapy. Coughing and deep breathing exercises (Choice C) are commonly used for clients at risk of respiratory complications, like postoperative patients. Monitoring the red blood cell count (Choice D) is important for conditions like anemia but is not the priority in a client with multiple myeloma, where fluid management is crucial.
