Question 1 of 5
Narrow therapeutic index medications:
Correct Answer: C
Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug. It provides a general indication of the margin of safety of a drug.
Choice 1 is incorrect because pharmacokinetics is the process of adsorption, distribution, metabolism, and elimination.
Choice 2 is incorrect because narrow therapeutic index drugs require close monitoring since there is often little difference between the desired drug effect and toxicity.
Choice 4 is incorrect because narrow therapeutic index drugs have the potential for severe toxic effects with only slight increases in the dose or slight decreases in elimination.
Question 2 of 5
During data collection of a client with suspected carpal tunnel syndrome, a nurse plans to perform the Phalen test. The nurse should ask the client to perform which activity?
Correct Answer: C
Rationale: In the Phalen test, the nurse asks the client to hold the hands back to back while flexing the wrists 90 degrees. This position puts pressure on the median nerve, eliciting symptoms in carpal tunnel syndrome. Dorsiflexing or plantarflexing the foot and hyperextending the fingers are not associated with testing for carpal tunnel syndrome. Acute flexion of the wrist for 60 seconds produces no symptoms in the normal hand.
Question 3 of 5
A nurse is preparing to listen to the apical heart rate in the area of the mitral valve in an adult client. The nurse should place the stethoscope on which part of the client's chest?
Correct Answer: D
Rationale: The correct placement for auscultating the apical heart rate in the area of the mitral valve is the fifth left interspace at the midclavicular line. Placing the stethoscope in the second left interspace would be to listen to the pulmonic valve, the second right interspace is for the aortic valve, and the left lower sternal border is for the tricuspid valve.
Question 4 of 5
A client is brought to the emergency department after a motor vehicle accident. The client is alert and cooperative but has sustained multiple fractures of the legs. How should the nurse proceed with data collection?
Correct Answer: B
Rationale: When a client is alert and cooperative but has sustained multiple fractures, the nurse should prioritize obtaining health history information while performing the examination and initiating emergency measures. This approach allows the nurse to gather essential information without delaying immediate interventions. Option A is incorrect because collecting health history information before addressing the immediate need for treatment may lead to a delay in necessary interventions. Option C is incorrect as it includes non-urgent aspects of data collection that are not a priority in this critical situation. Option D is incorrect because delaying health history questions until after treating the fractures may result in missing crucial information essential for the client's immediate care.
Question 5 of 5
Which of the following client groups should the nurse recognize as the fastest-growing segment of the homeless population?
Correct Answer: B
Rationale: Single mothers with two or three children are indeed the fastest-growing segment of the homeless population. These families, where the majority of children are under the age of five, make up more than one-third of the homeless population in the United States. While single, adult men have traditionally been the largest group in the homeless population, single mothers with children have been increasing in numbers. Runaway adolescents, although a significant group of homeless children, do not represent the fastest-growing segment of the homeless population. Single, adult women are not specified as the fastest-growing segment.
