Before administering an antibiotic that can cause nephrotoxicity, which laboratory value is most important for the practical nurse (PN) to review?

Serum calcium

Serum creatinine

Hemoglobin and Hematocrit

White blood cell count (WBC)

Answer and Explanation

The Correct Answer is B

Serum creatinine is the most important laboratory value to review before administering an antibiotic that can cause nephrotoxicity. Nephrotoxicity is an alteration in the function of the kidney due to exposure to certain drugs or toxins.

It can be assessed by measuring the glomerular filtration rate (GFR), which is the rate of clearance of a substance from the blood by the kidneys. Serum creatinine is a waste product of muscle metabolism that is freely filtered by the glomeruli and not reabsorbed or secreted by the tubules.

Therefore, it is a reliable indicator of GFR and renal function. An increase in serum creatinine indicates a decrease in GFR and renal function, which may be caused by nephrotoxic drugs.

The other laboratory values are not directly related to nephrotoxicity or GFR:

Serum calcium: This may be aﬀected by renal function, but it is not a sensitive or specific marker of nephrotoxicity. It may be altered by other factors such as vitamin D, parathyroid hormone, and bone metabolism.
Hemoglobin and hematocrit: These may be aﬀected by renal function, but they are not sensitive or specific markers of nephrotoxicity. They may reﬂect the erythropoietin production by the kidneys, which stimulates red blood cell production in the bone marrow. However, they may also be inﬂuenced by other factors such as blood loss, hydration status, and iron deficiency.
White blood cell count (WBC): This is not related to nephrotoxicity or GFR. It may reﬂect the presence of infection or inﬂammation, which may be a cause or a consequence of renal impairment, but it is not a direct measure of renal function.

Correct Answer is ["B","D"]

Explanation

The correct answer is choice b. Apple juice and d. Chicken broth.

Choice A rationale:

Orange juice is a clear liquid and generally acceptable on a clear liquid diet. However, it is not the best choice for someone following Mormon beliefs due to its acidity, which might not be suitable post-surgery.

Choice B rationale:

Apple juice is a clear liquid and suitable for a clear liquid diet. It is also non-caffeinated and non-alcoholic, aligning with Mormon dietary restrictions.

Choice C rationale:

Hot chocolate contains caffeine and is not considered a clear liquid. It is not suitable for a clear liquid diet and does not align with Mormon dietary restrictions.

Choice D rationale:

Chicken broth is a clear liquid and suitable for a clear liquid diet. It is non-caffeinated and non-alcoholic, making it appropriate for someone following Mormon beliefs.

Choice E rationale:

Black coffee contains caffeine, which is prohibited in the Mormon diet. It is also not recommended on a clear liquid diet.

A. The client is the oldest of their siblings. B. The client's father lives in the client's home. C. The client's mother has asthma. D. The client has several siblings.

Correct Answer is D

Explanation

Choice A rationale:

The client being the oldest of their siblings is not a contributing factor related to the development of conduct disorder. Family dynamics such as birth order may have some influence on personality traits, but they are not a primary factor in the development of conduct disorder.

Choice B rationale:

The fact that the client's father lives in the client's home is a family dynamic, but it does not necessarily contribute to the development of conduct disorder. Other factors related to parenting style, communication, and family interactions play a more significant role in the development of conduct disorder.

Choice C rationale:

The client's mother having asthma is a medical condition and not a family dynamic that directly contributes to the development of conduct disorder. Conduct disorder is more closely associated with social, environmental, and psychological factors.

Choice D rationale:

The presence of several siblings in the family dynamic can contribute to the development of conduct disorder. Increased family size can lead to competition for attention and resources, which may affect the child's behavior and interactions. Sibling relationships and family dynamics are crucial in shaping a child's behavior and psychological well-being.
