Before a cancer receiving total parenteral nutrition (TPN) resumes a normal diet, the nurse teaches him about dietary sources of minerals. Which foods are good sources of zinc?

Correct Answer: D

Rationale: The correct answer is D: Whole grains and meats. Zinc is found in high amounts in these foods. Meats, especially red meats and seafood, are rich sources of zinc. Whole grains like wheat, rice, and oats also contain significant amounts of zinc. Other choices are incorrect because fruits and vegetables are not typically good sources of zinc. Yeast and legumes are good sources of other minerals but not specifically zinc. It is important for the cancer patient to consume zinc-rich foods to support their immune system and overall health during recovery.

Correct Answer: D

Rationale: The correct answer is D: Understands discharge instructions. This is crucial for patient safety and recovery post-surgery. Understanding discharge instructions ensures patients know how to care for themselves at home, manage medications, recognize warning signs, and follow-up instructions. Choice A is incorrect as patients should not drive after surgery due to potential impairment. Choice B is incorrect as IV narcotics administration timing is not a discharge criterion. Choice C is irrelevant to the patient's readiness for discharge. Understanding discharge instructions is the key factor in ensuring the patient's well-being and recovery after ambulatory surgery.

Correct Answer: D

Rationale: The correct answer is D because morphine helps in acute pulmonary edema by decreasing peripheral resistance, pulmonary capillary pressure, and transudation of fluid. Morphine causes vasodilation, reducing peripheral resistance, which helps redistribute blood flow to the periphery. It also reduces pulmonary capillary pressure by decreasing preload and afterload, leading to decreased fluid transudation into the alveoli. Choices A, B, and C individually do not cover all the effects of morphine in acute pulmonary edema, making them incorrect.

Correct Answer: A

Rationale: Rationale: Right-sided heart failure leads to fluid backup in the body causing dependent pitting edema due to fluid accumulation in the lower extremities. Orthopnea and exertional dyspnea are typically seen in left-sided heart failure. Hemoptysis is associated with conditions like pulmonary embolism or lung cancer, not right-sided heart failure. Therefore, the correct answer is A as it directly correlates with the symptoms of right-sided heart failure.

Correct Answer: A

Rationale: Step 1: Regular aerobic exercise helps lower blood pressure by improving heart health and circulation. Step 2: Exercise reduces stress and promotes weight loss, factors that contribute to hypertension control. Step 3: Alcohol consumption can raise blood pressure and should be limited or avoided. Step 4: Smoking and using low-tar cigarettes can still raise blood pressure and have other negative health effects. Step 5: Daily multivitamin supplements do not directly impact blood pressure control.
