Correct Answer: B

Rationale: Parents should be taught not to cover the cord with a diaper to allow for air exposure and drying, preventing infection. The statement 'I should put alcohol on my baby's cord 3-4 times a day' indicates a need for further teaching as current recommendations do not include using alcohol on the cord, which can interfere with natural healing. While it is normal for the cord to turn dark as it dries, so the statement 'I should call the physician if the cord becomes dark' is accurate, it is not the best answer for this question. Washing hands before and after caring for the cord is important to prevent the transfer of pathogens, so this statement does not require further teaching.

Correct Answer: C

Rationale: The correct order of tasks when performing an abdominal assessment is to first inspect the abdomen visually, then auscultate to assess bowel sounds without altering them, followed by percussing to assess the presence of tympany or dullness, and finally palpating to feel for any tenderness, masses, or organ enlargement. Placing palpation or percussion before auscultation, as in choices A, B, and D, can affect the bowel sounds and examination findings, making them incorrect sequences.

Correct Answer: C

Rationale: The correct answer is, "I believe this new PCA pump will finally alleviate my back pain."? This statement indicates a need for additional education as it reflects an unrealistic expectation regarding pain management. It is essential for the patient to understand that while a PCA pump can provide effective pain relief, it may not completely eliminate pain. Option A is correct as it demonstrates the patient's understanding of the importance of reporting pain scores for proper pain management. Option B is correct as it shows the patient's awareness of the maximum dose limits to prevent overdose. Option D is correct as it highlights the patient's understanding of the control they have over their medication administration.

Correct Answer: D

Rationale: Scurvy is indeed associated with inadequate intake of vitamin C. Vitamin C deficiency leads to scurvy, which is characterized by weakness, anemia, gum disease, and skin hemorrhages. Choices A, B, and C are incorrect because rickets is caused by vitamin D deficiency, marasmus is due to severe malnutrition leading to wasting, and kwashiorkor is a form of severe protein-energy malnutrition.

Correct Answer: A

Rationale: The correct answer is 'every 24 hours.' Changing the intravenous tubing on total parenteral nutrition solutions every 24 hours is crucial due to the high risk of bacterial growth. Bacterial contamination can lead to serious infections in patients receiving total parenteral nutrition. Choices B, C, and D are incorrect because waiting longer intervals between tubing changes increases the risk of bacterial contamination and infection, compromising patient safety. It is essential to maintain a strict 24-hour schedule to minimize the risk of complications associated with bacterial contamination.
