Nclex Questions Management of Care

1. What is the term for the tendency of a drug to combine with its receptor?

A. potency
B. efficacy
C. kinetics
D. affinity

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

2. The client asks the nurse not to tell anyone outside of the care team about his positive HIV diagnosis. What response is most appropriate?

A. "I have to inform all clients on the unit of your diagnosis as it is transmissible."?
B. "I will not communicate your diagnosis to anyone without your permission."?
C. "Because this is a communicable disease, it may need to be reported to the CDC."?
D. "You should not be concerned with who I share your diagnosis with."?

Correct answer: C

Rationale: The most appropriate response is C: "Because this is a communicable disease, it may need to be reported to the CDC."? It is important to uphold patient confidentiality, but in the case of certain communicable diseases like HIV, there are legal requirements for mandatory reporting to public health authorities such as the CDC. Option A is incorrect because it violates patient confidentiality and does not consider legal obligations. Option B, while respecting the client's wishes, may not align with the legal requirement for reporting certain communicable diseases. Option D is inappropriate as it dismisses the client's concerns and rights regarding their health information.

3. Which of these would be an appropriate meal for a client with Celiac disease?

A. egg noodles with cream sauce and broccoli, oat cookie, almond milk
B. turkey sandwich with rye bread, carrots
C. chicken and rice, apple, and tapioca pudding
D. granola and dried apricots with cow's milk

Correct answer: C

Rationale: For individuals with Celiac disease, it's crucial to avoid gluten-containing foods. Choice C, which includes chicken, rice, apple, and tapioca pudding, is the most suitable option as all these foods are naturally gluten-free. Rice, fruits, vegetables, meat, dairy, and tapioca are all safe gluten-free options. Oats can be gluten-free if specially labeled, but many are processed on shared equipment with wheat. Granola often contains oats that may have been exposed to gluten. Dried and prepackaged fruits may contain gluten additives. Rye is a wheat derivative, and cream sauces usually contain flour as a base, making choices A and B inappropriate for individuals with Celiac disease.

4. A client is having an abortion in a women's clinic, and the nurse caring for the client does not think the reasoning is appropriate. The nurse asks, "Are you sure you want to do this? It can't be undone. Have you read about your other options? Adoption is always a good choice."? The client states she understands all options and is comfortable with her choice. The nurse nods and leaves the room to discuss the procedure with the physician. Which client right did the nurse violate with her actions?

A. the client's right to make personal health decisions without interference, as the nurse tried to sway the client's decision-making and healthcare choice in the direction of not having an abortion
B. the client's right to be left alone without unsolicited attention, as the nurse inserted herself in the client's healthcare scenario and offered uninvited advice
C. the client's right to confidentiality, as the nurse is talking to the physician about the client and the abortion
D. the client's right to respectful care, as the nurse clearly made it known that she did not approve of the abortion

Correct answer: A

Rationale: A client has the right to make decisions about their healthcare without interference from healthcare team members. In this scenario, the nurse violated the client's right to make personal health decisions without interference by trying to influence the client's decision-making and healthcare choice in the direction of not having an abortion. It is essential for healthcare providers to respect patients' autonomy and decisions, regardless of personal beliefs. Choices B, C, and D are incorrect because the primary violation in this situation is related to the client's right to make their own healthcare decisions without interference.

5. Pulling is easier than pushing. So pulling a client rather than pushing them has which of the following advantages?

A. reduces workload
B. decreases opposition from gravity
C. maintains stability
D. prevents muscle strain

Correct answer: A

Rationale: When pulling a client, you work with the gravitational force instead of opposing it, which reduces the workload on your muscles. Choosing to pull a client minimizes the effort required compared to pushing. Choice B is incorrect because the force of gravity remains constant regardless of pushing or pulling. Choice C is irrelevant as stability is not directly related to the advantage of pulling over pushing. Choice D is inaccurate because pulling can still strain muscles if not executed correctly, but it generally reduces the overall workload in comparison to pushing.
