Practice HESI Fundamentals Exam

Correct Answer: A

Rationale: The correct answer is A. Rolling the NPH vial between the hands before drawing it up ensures proper mixing of the insulin. Choice B is incorrect because regular insulin should be drawn up first to avoid contamination. Choice C is incorrect as injecting air into the vial of regular insulin is not necessary. Choice D is incorrect as there is no need to wait 10 minutes after mixing the insulin before injecting it.

Correct Answer: D

Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.

Correct Answer: A

Rationale: Choice A, '8 oz of ice chips,' is the correct answer. 8 oz is equivalent to approximately 240 mL, and since 1 oz is roughly equal to 30 mL, 8 oz would be approximately 240 mL. Since the question specifies 120 mL of fluid, this option does not match. Choices C and D, '1 cup of broth,' do not equate to 120 mL. A standard cup is approximately 240 mL, which is double the amount mentioned in the question. Therefore, choice A is the most accurate representation of 120 mL of fluid intake.

Correct Answer: A

Rationale: Addressing the client's daily needs and concerns is a priority to help alleviate anxiety and ensure the client understands the immediate post-MI care. Daily needs and concerns encompass basic aspects like comfort, hygiene, emotional support, and overall well-being, which are crucial in the early recovery phase post-MI. Discussing cardiac rehabilitation, medication and diet guidelines, or activity and rest guidelines are important topics but addressing immediate personal needs and concerns takes precedence to establish a supportive and informative care environment.

Correct Answer: C

Rationale: In a palliative care setting, when caring for a client approaching death with symptoms of shortness of breath and noisy respirations, using a fan can help alleviate the sensation of breathlessness. This intervention can provide comfort by improving air circulation and reducing the perception of breathlessness. Turning the client every 2 hours may not directly address the respiratory distress caused by noisy respirations. Providing supplemental oxygen may not be indicated or effective in all cases, especially in end-of-life care where the focus is on comfort rather than aggressive interventions. Administering diuretics as prescribed would not be appropriate for addressing noisy respirations and shortness of breath in a dying client, as this may not be related to fluid overload or congestion. Therefore, the most appropriate action to help the client feel more comfortable in this situation is to use a fan to reduce the feeling of breathlessness.
