1. Which of the following is an example of a positive effect of exercise on a client?

A. Decreased basal metabolic rate
B. Decreased venous return
C. Decreased work of breathing
D. Decreased gastric motility

Correct answer: C

Rationale: The correct answer is 'Decreased work of breathing.' Exercise has numerous positive effects on clients, such as increasing metabolic rate, improving gastric motility, and enhancing venous return. When a client exercises regularly, their work of breathing decreases, meaning that everyday activities require less exertion. This is beneficial as it indicates improved cardiovascular and respiratory efficiency. Choices A, B, and D are incorrect because a decreased basal metabolic rate, decreased venous return, and decreased gastric motility are not typically considered positive effects of exercise. Instead, an increased basal metabolic rate, improved venous return, and optimal gastric motility are desired outcomes associated with physical activity.

2. The nurse is examining a 2-year-old child and asks, "May I listen to your heart now?"? Which critique of the nurse's technique is most accurate?

A. Asking questions may enhance the child's autonomy.
B. Asking the child for permission helps develop a sense of trust.
C. This question is an inappropriate statement because children at this age like to have choices.
D. Children at this age like to say, "No."? The examiner should not offer a choice when no choice is available.

Correct answer: D

Rationale: Children at the age of 2 often like to assert their independence by saying "No."? In situations where there is actually no choice available, offering a false choice can lead to a lack of trust. It is important not to offer a choice when there isn't one, as doing so may undermine trust. While asking for permission can enhance autonomy and trust, offering a limited option like, "Shall I listen to your heart next or your tummy?"? may be a better approach. Therefore, the correct critique of the nurse's technique in this scenario is that children at this age tend to say "No,"? so the examiner should avoid offering a choice when there isn't a real alternative.

3. For a patient who is blood type AB, which blood product can they receive?

A. Plasma from a type B donor
B. Whole blood from a type A donor
C. Packed RBCs from a type O donor
D. All of the above

Correct answer: C

Rationale: A patient with blood type AB has AB antigens on their red blood cells. This means they can only receive blood products that are compatible with these antigens. Choice A is incorrect because an AB patient cannot receive plasma from a type B donor due to the antibodies present in type B plasma. Choice B is incorrect because an AB patient cannot receive whole blood from a type A donor as it contains incompatible antigens. Choice C is the correct answer because an AB patient can receive packed RBCs from a type O donor. Type O donors have no A or B antigens, making their blood compatible for transfusion to recipients with any blood type. Therefore, choices A and B are incorrect, and the correct choice is C.

4. After change-of-shift report, which patient should the nurse assess first?

A. 72-year-old with cor pulmonale who has 4+ bilateral edema in his legs and feet
B. 28-year-old with a history of a lung transplant and a temperature of 101 F (38.3 C)
C. 40-year-old with a pleural effusion who is complaining of severe stabbing chest pain
D. 64-year-old with lung cancer and tracheal deviation after subclavian catheter insertion

Correct answer: D

Rationale: The patient with lung cancer and tracheal deviation after a subclavian catheter insertion should be assessed first. Tracheal deviation can indicate tension pneumothorax, a life-threatening condition that requires immediate intervention to prevent inadequate cardiac output or hypoxemia. While the other patients also need assessment, the potential for tension pneumothorax in the patient with tracheal deviation necessitates urgent attention to prevent complications.

5. Which of the following lists the recommended sequence for removing soiled personal protective equipment when preparing to leave a patient's room?

A. Gown, goggles, mask, gloves, and exit the room.
B. Gloves, wash hands, remove gown, mask, and goggles.
C. Gloves, goggles, gown, mask, and wash hands.
D. Gloves, goggles, gown, mask, and wash hands.

Correct answer: D

Rationale: The correct sequence for removing soiled personal protective equipment is crucial to prevent contamination. Gloves should always be removed first as they are most likely to be contaminated. Following the removal of gloves, goggles, gown, mask, and finally washing hands is recommended. Choice A is incorrect as gloves should be removed first. Choice B is incorrect as the sequence is not in the recommended order. Choice D is incorrect as gloves should be removed before goggles.
