Nursing Elites

1. 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.

2. A nurse on the night shift is making client rounds. When the nurse checks a client who is 97 years old and has successfully been treated for heart failure, he notes that the client is not breathing. If the client does not have a do-not-resuscitate (DNR) order, the nurse should take which action?

• A. Administer cardiopulmonary resuscitation (CPR)
• B. Call the client's health care provider
• C. Administer oxygen to the client and call the health care provider
• D. Contact the nursing supervisor for directions

Correct answer: A

Rationale: Administering cardiopulmonary resuscitation (CPR) is the appropriate action when a client is not breathing and does not have a do-not-resuscitate (DNR) order. CPR is considered an emergency treatment that can be provided without client consent in life-threatening situations. Calling the health care provider or nursing supervisor for directions, as well as administering oxygen without addressing the lack of breathing, would delay critical life-saving interventions. Therefore, administering CPR is the most urgent and necessary action to perform in this scenario.

3. Which of the following isoenzymes is elevated in a client who has had a myocardial infarction?

• A. CPK-BB
• B. CPK-MM
• C. CPK-MB
• D. CPK-MI

Correct answer: C

Rationale: CPK-MB is the correct answer as it is elevated in clients who have had a myocardial infarction. CPK-BB is elevated in clients with brain damage, and CPK-MM is elevated in clients with skeletal muscle damage. CPK-MI, mentioned in the rationale, does not exist, making it an incorrect choice.

4. While working the 11 p.m. to 7 a.m. shift at the long-term care unit, the nurse gathers the nursing staff to listen to the 3 to 11 p.m. intershift report. The nurse notes that a staff member has an odor of alcohol on her breath, slurred speech, and an unsteady gait, suspecting alcohol intoxication. What is the most appropriate action for the nurse to take?

• A. Contact the nursing supervisor.
• B. Tell the staff member that she is not allowed to administer medications.
• C. Ask the staff member how much alcohol she has consumed.
• D. Ask the staff member to rest in the nurses' lounge until the effects of the alcohol wear off.

Correct answer: A

Rationale: When a staff member reports to work showing signs of alcohol intoxication, the nurse should objectively note the symptoms and ask a second person to confirm these observations. It is crucial to contact the nursing supervisor immediately. An odor of alcohol, slurred speech, unsteady gait, and errors in judgment are indicators of intoxication, posing a risk to client safety. The staff member should be removed from the client care area. Detailed documentation of the incident is essential, including observations, actions taken, future plans, and the staff member's signature and date on the recorded incident memo. If the staff member refuses to sign, this should be noted by the nurse and a witness. Asking the staff member to rest in the nurses' lounge or restricting medication administration does not ensure client safety, as the staff member could still jeopardize it. Inquiring about the amount of alcohol consumed is confrontational and not relevant to the immediate need of ensuring safety.

5. A primigravida begins labor when her family is unavailable and she is alone. She is very upset that her family is not with her. Which approach can the nurse take to meet the client's needs at this time?

• A. asking whether another individual wants to be her support person
• B. assuring her that a nursing staff member will be with her at all times
• C. telling her you will try to locate her family
• D. reinforcing the woman's confidence in her own abilities to cope and maintain a sense of control

Correct answer: A

Rationale: In this situation, the best approach for the nurse is to ask whether another individual wants to be the client's support person. This empowers the client to choose someone to be with her until her family can join her, providing the needed support and comfort. Assuring her that a nursing staff member will be with her at all times (Choice B) may not fully address her emotional needs for familiar support. Telling her you will try to locate her family (Choice C) may not be feasible in the immediate situation and may not provide immediate emotional support. While reinforcing the woman's confidence in her own abilities (Choice D) is important, it may not fully address her current need for emotional support and presence of a companion.
