A nurse is caring for a client who has a magnesium level of 3.2 mEq/L. Which of the following medications should the nurse expect to administer?

The nurse should report a creatinine level of 2 mg/dl to the provider as a potential adverse effect of captopril. Captopril is an angiotensin-converting enzyme (ACE) inhibitor commonly used to treat congestive heart failure and hypertension. One of the side effects of ACE inhibitors, including captopril, is the potential to cause kidney problems, leading to an increase in serum creatinine levels.

An increase in serum creatinine may indicate impaired kidney function, and it is essential to monitor kidney function regularly in clients taking ACE inhibitors. Elevated creatinine levels can suggest reduced glomerular filtration rate (GFR) and impaired kidney function, which may require adjustments in medication dosage or further evaluation and management.

Let's go through the other options:

A. Absolute neutrophil count (ANC) 4.000/ mm^3: An absolute neutrophil count of 4.000/ mm^3 is within the normal range, so it is not an adverse effect of captopril that requires immediate reporting.

B. Brain natriuretic peptide (BNP) 90 ng/L: A brain natriuretic peptide (BNP) level of 90 ng/L is used to assess heart failure severity. While BNP levels can be helpful in managing congestive heart failure, a BNP level of 90 ng/L is not an adverse effect of captopril that requires immediate reporting.

C. Sodium 140 mEq/l: A sodium level of 140 mEq/L is within the normal range, so it is not an adverse effect of captopril that requires immediate reporting.

Neonatal abstinence syndrome (NAS) is a group of withdrawal symptoms that occur in newborns who were exposed to drugs, including heroin, in utero. Hyporeflexia, which refers to reduced or diminished reflexes, is one of the key findings in neonates experiencing NAS.

During pregnancy, when the mother uses opioids like heroin, the baby becomes dependent on the drug. After birth, when the drug is no longer available, the baby experiences withdrawal symptoms as the body adjusts to the absence of the drug. Hyporeflexia is a common manifestation of NAS and is observed due to the central nervous system's response to the withdrawal.

Let's go through the other options:

B. Frequent yawning: While yawning can be seen in neonates with NAS, it is not as specific to the condition as hyporeflexia. Yawning can occur for various reasons and may not always be indicative of NAS.

C. Respiratory depression: Respiratory depression can be a severe complication of opioid exposure in utero and can result in life-threatening situations for the neonate. However, it is not specific to NAS. Respiratory depression is more closely associated with opioid overdose in the newborn, which can be a separate concern from NAS.

D. Constipation: Constipation is a possible symptom in neonates experiencing NAS, but it is not as specific as hyporeflexia. Constipation can occur due to various factors and is not unique to NAS.
