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 is assigned to care for four clients. Which client should the nurse assess first?

• A. A client scheduled for a colonoscopy
• B. A client with a tracheostomy who is receiving humidified oxygen via a tracheostomy mask
• C. A client preparing for discharge after surgery
• D. A client requiring a tube feeding through a gastrostomy tube

Correct answer: B

Rationale: The correct answer is a client with a tracheostomy who is receiving humidified oxygen via a tracheostomy mask. Airway management is always the priority in nursing care. Assessing this client first ensures that their airway is clear and oxygenation is adequate. Clients with compromised airways need immediate attention to prevent respiratory distress or failure. The other clients do not have immediate airway concerns and represent lower priorities in this scenario. Therefore, the nurse should prioritize assessing the client with the tracheostomy and oxygen therapy to maintain airway patency and adequate oxygenation.

3. If a visitor accidentally knocks over a plastic pleural drainage system connected to a client, causing it to crack, what should the nurse do first?

• A. Observe the client's response.
• B. Notify the physician.
• C. Change the drainage system.
• D. Observe for leaks.

Correct answer: C

Rationale: When a pleural drainage system is cracked, the nurse's initial action should be to change the drainage system. This is essential to prevent potential complications like air leaks or infections. While observing the client's response and checking for leaks are important steps, they are secondary to addressing the immediate issue of the cracked system. Notifying the physician, though necessary, can be carried out once the primary concern of the damaged system is resolved.

4. The LPN is checking for residual before administering enteral feeding through a PEG tube. Which of these steps is incorrect?

• A. The LPN elevates the head of the bed by at least 30 degrees.
• B. If the residual is greater than 200mL, the LPN should not administer the enteral feeding.
• C. The LPN should discard the residual before administering the tube feeding.
• D. The residual pH level is tested to ensure appropriate placement.

Correct answer: C

Rationale: The incorrect step is choice C. The residual should be discarded before administering the tube feeding. Discarding the residual is essential to prevent contamination and ensure accurate measurement of the enteral feeding. Elevating the head of the bed by at least 30 degrees (choice A) is correct as it helps prevent aspiration during feeding. Testing the pH level of the residual (choice D) ensures proper placement of the tube. Withholding feeding if the residual is greater than 200mL (choice B) is crucial to prevent overfeeding, making this statement correct.

5. A safety measure to implement when transferring a client with hemiparesis from a bed to a wheelchair is:

• A. standing the client and walking him or her to the wheelchair.
• B. moving the wheelchair close to the client's bed and standing and pivoting the client on his unaffected extremity to the wheelchair.
• C. moving the wheelchair close to the client's bed and standing and pivoting the client on his affected extremity to the wheelchair.
• D. having the client stand and push his body to the wheelchair.

Correct answer: B

Rationale: When transferring a client with hemiparesis from a bed to a wheelchair, it is crucial to ensure their safety. The correct safety measure involves moving the wheelchair close to the client's bed and having the client stand and pivot on his unaffected extremity to the wheelchair. This method provides support with the unaffected limb, reducing the risk of falls and promoting a safer transfer. Choice A is incorrect because walking the client is unsafe and not recommended. Choice C is incorrect as pivoting the client on his affected extremity can lead to injury or falls due to weakness or lack of control. Choice D is incorrect as it puts the client at risk by requiring them to push their body, which may not be feasible or safe for someone with hemiparesis.
