Correct Answer: B

Rationale: The correct answer is B: Ask her to demonstrate her ability to ambulate. This response is best because it allows the nurse to assess the patient's actual ability to walk safely to the bathroom. By observing her, the nurse can ensure her safety and prevent potential falls. This approach also respects the patient's autonomy while prioritizing her safety. Incorrect responses: A: Allowing her to ambulate unassisted solely for positive self-esteem overlooks the importance of assessing her actual capability and ensuring safety. C: Explaining that assistance will always be available may not address the immediate need for assessment and safety. D: Asking another staff member to assist without assessing the patient's ability herself does not allow the nurse to directly evaluate the patient's safety and independence.

Correct Answer: D

Rationale: The correct answer is D: Sitting at a 45-degree angle to the bed. This position allows the nurse to have a clear view of the client and maintain good communication. Sitting at a 45-degree angle enables the nurse to observe the client's facial expressions, body language, and interact effectively. Standing at the end of the bed (A) limits the nurse's view and communication. Standing at the side of the bed (B) may obstruct the nurse-client interaction. Sitting at least six feet away (C) creates unnecessary distance and hinders effective communication.

Correct Answer: C

Rationale: The correct answer is C because compatibility between blood donor and recipient is determined by the absence of clumping or hemolysis when both samples are mixed. Clumping indicates an incompatible blood type reaction, leading to potential harm. Blood clots (option B) are not indicative of compatibility but rather a sign of coagulation issues. Blood color change (option A) and blood drop sinking in water (option D) are not reliable indicators of blood compatibility. In summary, option C is correct as it directly assesses for the absence of a harmful reaction, while the other choices do not accurately determine blood compatibility.

Correct Answer: D

Rationale: The correct answer is D because a multilumen pulmonary artery catheter can provide detailed information about preload, afterload, and cardiac output. Preload refers to the volume of blood in the ventricles at the end of diastole, afterload is the resistance the heart has to overcome to eject blood, and cardiac output is the amount of blood pumped by the heart per minute. This catheter allows for direct measurement of these parameters by monitoring pressures in the pulmonary artery. Choices A, B, and C are incorrect individually as they do not encompass the full range of information that can be obtained with a multilumen pulmonary artery catheter.

Correct Answer: A

Rationale: The correct answer is A: Positive family history. Pernicious anemia is an autoimmune condition where the body attacks its own intrinsic factor, leading to vitamin B12 deficiency. Genetic predisposition plays a significant role in the development of pernicious anemia. Family history is a key risk factor as individuals with a family history of pernicious anemia are more likely to develop the condition. Summary of why the other choices are incorrect: B: Infectious agents or toxins do not directly cause pernicious anemia, although they can lead to other types of anemia. C: Acute or chronic blood loss can result in iron-deficiency anemia, not pernicious anemia. D: Inadequate dietary intake of vitamin B12 can lead to vitamin B12 deficiency anemia, but pernicious anemia specifically involves the body's inability to absorb B12 due to intrinsic factor deficiency, not dietary intake alone.
