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 client scheduled for a left mastectomy and axillary lymph node dissection is wearing a wedding band on her left ring finger. The nurse should take which action?

• A. Tape the wedding band in place
• B. Ask the client to sign a release freeing the hospital of responsibility if the wedding band is lost during surgery
• C. Explain to the client why the wedding band must be removed
• D. Ask the client whether she would like to remove the wedding band or wear it to surgery

Correct answer: C

Rationale: In most situations, a wedding band may be taped in place and worn during a surgical procedure. However, if there is a possibility that the client will experience swelling of the hand or fingers, the wedding band should be removed. On admission to a healthcare facility, the client is usually asked to sign a form that releases the agency from responsibility if a client's valuables are lost. After a mastectomy with axillary lymph node dissection, the client is at risk for lymphedema, which can result in swelling of the arm and hand on the affected side. Therefore, the appropriate nursing action is to ask the client to remove the wedding band and explain why. This ensures the client's safety and prevents potential complications. Option A is incorrect because taping the wedding band may not be sufficient if swelling occurs. Option B is incorrect as it does not address the immediate need to remove the wedding band. Option D is incorrect because it fails to provide the client with the necessary information about the potential risks of wearing the wedding band during surgery.

3. In a disaster triage situation, which of the following should the nurse be least concerned with regarding a client in crisis?

• A. ability to breathe
• B. pallor or cyanosis of the skin
• C. number of accompanying family members
• D. motor function

Correct answer: C

Rationale: During a disaster triage situation where quick decisions are crucial, the nurse's primary focus should be on factors directly related to the patient's immediate condition and survival. The ability to breathe, pallor or cyanosis of the skin, and motor function are critical indicators of a patient's health status and need for urgent intervention. In contrast, the number of accompanying family members, although important for emotional support, is not a priority when assessing and prioritizing care during a crisis. While emotional support is valuable, the focus in triage is on identifying and addressing the most critical and life-threatening issues first to maximize survival chances. Therefore, the nurse should be least concerned with the number of accompanying family members as it does not directly impact the patient's immediate medical needs in a crisis situation. Choices A, B, and D are all crucial factors to assess a client's health status and determine the urgency of intervention during a disaster triage. The ability to breathe indicates respiratory function, pallor or cyanosis of the skin reflect circulatory and oxygenation status, and motor function can hint at neurological impairment or injury, all of which are vital in determining the severity of the crisis and the immediate medical needs of the patient.

4. What is the 24-hour day-night cycle known as?

• A. circadian rhythm
• B. infradian rhythm
• C. ultradian rhythm
• D. non-REM rhythm

Correct answer: A

Rationale: The correct answer is circadian rhythm. Circadian rhythm refers to the rhythmic repetition of patterns that occur approximately every 24 hours, regulating various biological processes related to the day-night cycle. Infradian rhythm, which is longer than 24 hours, and ultradian rhythm, which is shorter than 24 hours, are not the correct terms for the 24-hour cycle. Non-REM rhythm does not specifically relate to the 24-hour day-night cycle, making it an incorrect choice.

5. An LPN is caring for a primarily bedridden client. Which finding should be of least concern?

• A. swollen feet
• B. brown discoloration above the ankles
• C. leg pain
• D. capillary refill time of 3 seconds on the big toe

Correct answer: D

Rationale: The correct answer is the capillary refill time of 3 seconds on the big toe. A capillary refill time longer than three seconds may indicate inadequate blood flow. Swollen feet, brown discoloration above the ankles, and leg pain are all signs of venous insufficiency to the lower extremities. These findings can suggest circulation issues and require further assessment and intervention. Therefore, they should be of more concern compared to the capillary refill time of 3 seconds on the big toe, which is within the normal range of 2-3 seconds.
