Correct Answer: A

Rationale: The correct answer is A because enemas can cause injury to a thrombocytopenic client due to the risk of bleeding. Choices B, C, and D are correct precautions for a client with thrombocytopenia. Using an electric shaver reduces the risk of cuts that could lead to bleeding. Eating soft, cool, or warm food helps prevent injuries to the oral mucosa. Avoiding activities like sports that carry a risk of injury is also advisable.

Correct Answer: C

Rationale: The correct choice is 'Baked apricot chicken and steamed broccoli' because fruits and vegetables have been shown to reduce the risk of cancer. Option A, smoked salmon and green beans, although a healthy choice, does not incorporate as many cancer-fighting foods as the correct answer. Option B, pork chops and fried green tomatoes, contains fried food which is associated with increased cancer risk. Option D, liver, onions, and steamed peas, includes organ meats which are not considered beneficial for reducing cancer risk.

Correct Answer: C

Rationale: In the context of AML, the 5-year survival rate significantly decreases with age. The 5-year survival rate for patients over 75 years old is less than 2% compared to 43% for those 50 years or younger, and 19% for those between 50 and 64 years. Choice A is incorrect as early diagnosis does not necessarily guarantee good outcomes in AML. Choice B is inaccurate as the 5-year survival rate is not approximately 50% for older adults with AML. Choice D is incorrect as survival rates for AML patients are influenced by various factors beyond just the pre-illness level of health.

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.

Correct Answer: D

Rationale: The correct answer is D because the statement 'Chemotherapy is effective in killing all cancer cells' is incorrect. Chemotherapy does not kill all cancer cells and is not the same as radiation therapy. Chemotherapy targets rapidly dividing cells, including cancer cells, but it may not kill every single cancer cell. It is important for the student nurse to understand and communicate this distinction to the patient. Choices A, B, and C provide accurate information about teletherapy, brachytherapy, and chemotherapy, respectively, and do not require additional teaching.
