Before administering an antibiotic that can cause nephrotoxicity, which laboratory value is most important for the practical nurse (PN) to review?
White blood cell count (WBC).
Serum creatinine.
Hemoglobin and Hematocrit.
Serum calcium
The Correct Answer is B
The correct answer is choice B, Serum creatinine. Choice A rationale:
The white blood cell count (WBC) is an important parameter for assessing the body's immune response to infections. While it can provide valuable information about the presence of an infection, it is not directly related to nephrotoxicity. Therefore, it is not the most important laboratory value to review before administering an antibiotic that can cause nephrotoxicity.
Choice B rationale:
Serum creatinine is a crucial laboratory value to assess kidney function. It is a waste product that is filtered by the kidneys, and its level in the blood is a reliable indicator of kidney function. If the serum creatinine level is elevated, it suggests impaired kidney function, which can be a warning sign of nephrotoxicity. Reviewing the serum creatinine level before administering nephrotoxic antibiotics is essential to ensure that the client's kidneys are functioning adequately and to avoid potential harm.
Choice C rationale:
Hemoglobin and hematocrit are indicators of the client's red blood cell count and blood's oxygen-carrying capacity. While these values can provide information about the client's overall health status, they are not directly related to nephrotoxicity. Therefore, they are not the most important laboratory values to review in this particular scenario.
Choice D rationale:
Serum calcium levels are essential for assessing bone health, nerve function, and muscle contractions. However, they are not directly related to nephrotoxicity, and reviewing serum calcium levels alone would not provide sufficient information about kidney function. Hence, it is not the most critical value to review before administering nephrotoxic antibiotics

Explanation
Digoxin is a medication used to treat various heart conditions, such as abnormal heart rhythms and heart failure.It works by improving the strength and efficiency of the heart, or by controlling the rate and rhythm of the heartbeat.
One of the important things to monitor when giving digoxin to an infant is the pulse rate. Digoxin can lower the heart rate, which can be dangerous if it becomes too slow.Therefore, the pulse rate should be checked for one full minute before administering digoxin, and the medication should be held if the pulse rate is below 90 beats per minute (bpm) for an infant.
In this case, the infant’s heart rate is 120 bpm, which is within the normal range for a 2-month-old. Therefore, the correct action for the PN to take is to administer the medication and document the heart rate. This is optionbin the list of choices. Optionais incorrect because there is no need to hold the medication or recheck the heart rate in one hour. Optioncis incorrect because there is no need to alert the charge nurse unless there is a problem with the infant’s condition or the medication. Optiondis incorrect because holding the medication and documenting cardiac assessment is not appropriate for a normal heart rate.
Correct Answer is B
Explanation
The Herpes zoster (shingles) vaccination is recommended for adults aged 60 years and older, regardless of whether they have had shingles or chicken pox before. The vaccine can reduce the risk of developing shingles and its complications, such as postherpetic neuralgia.
The other options are not correct because:
A. The vaccine is useful even if the person has had a case of shingles before, as shingles can recur in some people. The vaccine can prevent or reduce the severity of future episodes.
C. The person needs to get this vaccination even if they have had chickenpox, as shingles are caused by the reactivation of the same virus that causes chickenpox (varicella-zoster virus). The vaccine can boost the immunity against the virus and prevent it from reactivating.
D. The vaccination does not minimize outbreaks of cold sores, as cold sores are caused by a different virus (herpes simplex virus). The vaccine has no effect on this virus or its symptoms.
