Nursing Elites

1. The healthcare professional seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?

• A. urinalysis
• B. creatinine and blood urea nitrogen
• C. chemistry of electrolytes
• D. creatinine clearance

Correct answer: D

Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.

2. When the nurse is determining the appropriate size of an oropharyngeal airway to insert, what part of a client's body should she measure?

• A. corner of the mouth to the tragus of the ear
• B. corner of the eye to the top of the ear
• C. tip of the chin to the sternum
• D. tip of the nose to the earlobe

Correct answer: B

Rationale: Correct! When sizing an oropharyngeal airway, the nurse should measure from the corner of the client's mouth to the tragus of the ear. This measurement ensures that the airway is the appropriate length to reach the pharynx without being too long or too short. Choices B, C, and D are incorrect as they do not provide the correct anatomical landmarks for determining the size of an oropharyngeal airway. Measuring from the corner of the mouth to the tragus of the ear is a standard method to ensure proper airway size and prevent complications during airway management.

3. A client with cirrhosis of the liver presents with ascites. The physician is to perform a paracentesis. For safety, the nurse should ask the client to:

• A. drink 1000 cc of fluid prior to the procedure to aid in fluid loss.
• B. eat foods low in fat.
• C. empty his bladder prior to the procedure.
• D. assume the prone position.

Correct answer: C

Rationale: When performing a paracentesis, the client must be sitting up to allow the fluid to settle in the lower abdomen. To prevent trauma to the bladder while inserting a needle to aspirate the fluid, the bladder must be empty. Choice A is incorrect as excessive fluid intake can make the procedure more difficult due to increased abdominal distension. Choice B is unrelated to the procedure of paracentesis. Choice D is incorrect as the client should be sitting up, not in the prone position, during the procedure.

4. A client with a closed chest tube drainage system accidentally disconnects the chest tube while being turned by the nurse. What should the nurse do first?

• A. Submerge the end of the chest tube in a bottle of sterile water
• B. Clamp the chest tube with a Kelly clamp
• C. Call the health care provider
• D. Instruct the client to inhale and hold his breath

Correct answer: A

Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.

5. Nurses caring for clients who have cancer and are taking opioids need to assess for all of the following except:

• A. tolerance.
• B. constipation.
• C. sedation.
• D. addiction.

Correct answer: D

Rationale: When caring for clients with cancer who are taking opioids, nurses need to assess for tolerance, constipation, and sedation as these are common side effects of opioid use. Addiction, however, is not a primary concern when treating pain in terminally ill clients. Terminally ill patients are usually not at risk of developing addiction to opioids due to their short life expectancy and the focus on pain management rather than the potential for addiction. Therefore, the correct answer is 'addiction.' Choices A, B, and C are essential considerations when managing clients on opioids for pain control.
