1. A test that can correctly identify those who do not have a given disease is:
- A. specific.
- B. sensitive.
- C. negative culture
- D. marginal finding.
Correct answer: A
Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.
2. The client is unsure about making medical decisions as their disease progresses and wants to appoint someone to make these decisions. Which of the following options would be most appropriate?
- A. a living will
- B. informed consent
- C. a healthcare proxy
- D. non-informed consent
Correct answer: C
Rationale: The correct answer is 'a healthcare proxy.' A healthcare proxy involves the client appointing an individual to make medical decisions on their behalf if they become unable to do so. This option allows the client to choose someone they trust to act in their best interests. Choice A, 'a living will,' is a legal document that outlines a person's wishes regarding medical treatment in case they are unable to communicate their decisions. While it is important, it does not involve appointing someone to make decisions. Choice B, 'informed consent,' is a process where a healthcare provider explains a treatment or procedure, including its risks and benefits, to a patient who can then decide whether to proceed. This is not about appointing someone to make decisions on the patient's behalf. Choice D, 'non-informed consent,' is not a valid concept in healthcare. Informed consent is crucial for respecting a patient's autonomy and decision-making capacity.
3. Which of the following lab values is elevated first after a client has a myocardial infarction?
- A. LDH
- B. troponin
- C. CPK
- D. SGOT
Correct answer: B
Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.
4. The mother of a child who weighs 45 lb asks a nurse about car safety seats. The nurse tells the mother to place the child in which car safety seat?
- A. Car safety seat in the back seat in a face-forward position
- B. Booster seat with one of the car's seat belts placed over the child
- C. Booster seat in a rear-facing position in the front seat
- D. Car safety seat in a face-forward position in the front seat
Correct answer: B
Rationale: The correct answer is to place the child in a booster seat with one of the car's seat belts placed over the child. A child needs to remain in a car safety seat until he or she weighs 40 lb. Once the child has outgrown the car safety seat, a booster seat is used. Booster seats are designed to raise the child high enough so that the restraining straps are correctly positioned over the child's chest and pelvis, providing optimal safety. Placing a child in a booster seat in a rear-facing position in the front seat is incorrect as children should not be seated in the front seat due to potential airbag-related injuries. Additionally, car safety seats are used for children weighing less than 40 lb and are placed in the middle of the back seat in a rear-facing position for maximum protection.
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.
