Which of the following is not a function of parathyroid hormone?
- A. moving calcium from bones to the bloodstream
- B. inhibiting renal tubular reabsorption of phosphorus
- C. promoting renal tubular reabsorption of calcium
- D. enhancing renal production of vitamin D metabolites
Correct Answer: B
Rationale: The correct answer is 'inhibiting renal tubular reabsorption of phosphorus.' Parathyroid hormone actually inhibits renal tubular reabsorption of phosphorus, making this choice the opposite of its function. Parathyroid hormone functions to move calcium from bones to the bloodstream (Choice A), promote renal tubular reabsorption of calcium (Choice C), and enhance renal production of vitamin D metabolites (Choice D). Therefore, all other choices are functions of parathyroid hormone except for the inhibition of phosphorus reabsorption.

Upon first meeting, a new nurse manager makes eye contact, smiles, initiates conversation about the previous work experience of nurses, and encourages active participation by nurses in the dialogue. Her behavior is an example of:
- A. Aggressiveness.
- B. Passive aggressiveness.
- C. Passiveness.
- D. Assertiveness.
Correct Answer: D
Rationale: The correct answer is 'Assertiveness.' This nurse manager is demonstrating assertive behavior by confidently engaging with the nurses, showing interest in their work experience, and encouraging active participation. Aggressive behavior is forceful and dominating, while passive behavior is submissive and timid. Passive-aggressive behavior involves indirect manipulation or control, which is not demonstrated in this scenario.
Which of the following foods might a client with hypercholesterolemia need to decrease intake of?
- A. broiled catfish
- B. hamburgers
- C. wheat bread
- D. fresh apples
Correct Answer: B
Rationale: A client with hypercholesterolemia needs to decrease intake of foods that are high in cholesterol. Red meats like hamburgers are high in cholesterol, so their consumption should be reduced. Broiled catfish, wheat bread, and fresh apples are not high in cholesterol and do not need to be decreased in the client's diet. Therefore, the correct answer is hamburgers, as they are more likely to contribute to elevated cholesterol levels compared to the other options provided.
Quality is defined as a combination of all of the following except:
- A. conforming to standards.
- B. performing at the minimally acceptable level.
- C. meeting or exceeding customer requirements.
- D. exceeding customer expectations.
Correct Answer: B
Rationale: Quality in any context is about meeting or exceeding customer requirements and exceeding customer expectations. It also involves conforming to standards to ensure consistency and reliability. Merely performing at the minimally acceptable level does not encompass the essence of quality, as it sets the bar at the lowest level of acceptability rather than aiming for excellence or customer satisfaction. Therefore, the correct answer is 'performing at the minimally acceptable level,' as this choice falls short in capturing the comprehensive definition of quality.
A 4-year-old client is unable to go to sleep at night in the hospital. Which nursing intervention best promotes sleep for the child?
- A. turning off the room light and closing the door
- B. engaging the child in calming activities before bedtime
- C. identifying the child's home bedtime rituals and following them
- D. encouraging relaxation techniques like deep breathing exercises
Correct Answer: C
Rationale: For a 4-year-old client struggling to sleep in the hospital, the best nursing intervention is to identify the child's home bedtime rituals and follow them. Preschool-age children often have specific bedtime routines that provide comfort and promote sleep. This familiarity can help create a sense of security in an unfamiliar hospital environment. Choice A, turning off the room light and closing the door, may increase the child's fear of the dark and being alone. Choice B, engaging the child in calming activities before bedtime, is a better choice than tiring them with play exercises. Choice D, encouraging relaxation techniques like deep breathing exercises, although helpful, may not be as effective as following the child's familiar bedtime routines.
Following a recent tattoo, someone should be screened for:
- A. tuberculosis.
- B. herpes.
- C. hepatitis.
- D. syphilis.
Correct Answer: C
Rationale: Following a recent tattoo, someone should be screened for hepatitis. Tattooing puts a client at risk for blood-borne hepatitis B or C if strict sterile procedures are not followed. Tuberculosis is an airborne pathogen, while herpes and syphilis are spread through direct contact like sexual activity. Therefore, hepatitis is the most relevant infection to screen for after getting a tattoo.
