1. What is the best intervention for a patient experiencing hypoxia?

Correct answer: A

Rationale: The best intervention for a patient experiencing hypoxia is to administer oxygen. Oxygen therapy helps improve oxygenation levels in the blood, addressing the underlying cause of hypoxia. Repositioning the patient, providing humidified air, and chest physiotherapy may be beneficial in certain situations but are not the primary interventions for hypoxia. Administering oxygen is crucial to quickly alleviate hypoxia and support the patient's respiratory function.

2. The understanding of genetic influences on behavior may never be fully achieved due to ________.

Correct answer: B

Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.

3. A nurse is caring for a patient with heart failure who has developed pulmonary edema. What is the nurse's priority action?

Correct answer: B

Rationale: The correct answer is to place the patient in a high Fowler's position. This position helps improve lung expansion and oxygenation in cases of pulmonary edema by reducing venous return to the heart and enhancing respiratory mechanics. Administering a diuretic (Choice A) can be important but is not the priority over positioning in this situation. Administering oxygen (Choice C) is essential, but the priority action for improving oxygenation is the positioning of the patient. Monitoring lung sounds (Choice D) is crucial for ongoing assessment but is not the priority action when the patient is in distress with pulmonary edema.

4. Homeostasis exists if concentrations of water, nutrients, and oxygen in the body and heat and pressure __________.

Correct answer: remain within certain limited ranges

Rationale: Homeostasis is the body's ability to maintain stable internal conditions despite external changes. To achieve this balance, concentrations of essential substances must remain within specific ranges. Choice A is incorrect because decreasing concentrations would not maintain stability. Choice C is incorrect as increasing concentrations when the body is stressed would disrupt homeostasis. Choice D is incorrect as fluctuating greatly between high and low values would also not support the body's stability. Therefore, the correct answer is B, as it aligns with the concept of homeostasis by emphasizing the need for stability within certain limits.

5. When caring for a patient with major depressive disorder prescribed an MAOI, what type of food should the nurse educate the patient to avoid?

Correct answer: C

Rationale: Patients prescribed MAOIs need to avoid consuming tyramine-rich foods as these can lead to hypertensive crises. Tyramine is found in various foods like aged cheeses, cured meats, some types of beer, and fermented products. Interactions between tyramine and MAOIs can result in severe hypertension, highlighting the importance of educating patients about dietary restrictions to ensure their safety. Choices A, B, and D are incorrect because high-protein foods, high-fiber foods, and low-fat foods do not pose a significant risk of hypertensive crises when taken with MAOIs. Therefore, the correct answer is C.
