The practical nurse (PN) is providing care for a client who is receiving an aminoglycoside to treat a bacterial infection. To assess for signs of ototoxicity, which action should the PN take?

The infant has hypoglycemia, which is a low blood glucose level that can cause jitteriness, lethargy, seizures, or coma. Hypoglycemia is common in infants of mothers with gestational diabetes, as they produce excess insulin in response to high maternal glucose levels. The PN should begin frequent feedings of breast milk or formula, as this can provide a source of glucose and stimulate the infant's own glucose production.

The other options are not correct because:

A. Offering nipple feedings of 10% dextrose may be indicated in some cases of severe hypoglycemia, but it is not the first intervention. The PN should try oral feedings of breast milk or formula first, as they are more natural and less invasive.

C. Repeating the heel stick for glucose in one hour may be necessary to monitor the infant's glucose level, but it is not the first intervention. The PN should treat the hypoglycemia first, as it can have serious consequences if left untreated.

D. Assessing for signs of hypocalcemia may be important, as hypocalcemia is another possible complication in infants of mothers with gestational diabetes, but it is not the first intervention. The PN should address the hypoglycemia first, as it is more urgent and more likely to cause jitteriness.

Troponin I and CK-MB are cardiac enzymes that are released into the bloodstream when the heart muscle is injured or necrotic. Elevated levels of these enzymes indicate that the client has suffered a myocardial infarction (MI) or heart attack. The damaged heart tissue can impair the electrical conduction system of the heart and cause abnormal heart rhythms or dysrhythmias, which can be life-threatening. The PN should monitor the client's cardiac status closely and report any changes to the charge nurse.

The other options are not correct because:

B. The client is not at risk for pulmonary embolism, which is a blockage of a pulmonary artery by a blood clot or other material. Pulmonary embolism does not cause elevated cardiac enzymes, but it can cause chest pain, shortness of breath, and hypoxia.

C. The client is not at risk for recurrent long-term angina pain, which is chest pain caused by reduced blood flow to the heart muscle due to narrowed or blocked coronary arteries. Angina pain does not cause elevated cardiac enzymes, but it can be a warning sign of an impending MI.

D. The lab results do not indicate risk factors for transient ischemic attack (TIA), which is a temporary interruption of blood flow to a part of the brain due to a clot or plaque. TIA does not cause elevated cardiac enzymes, but it can cause neurological symptoms such as weakness, numbness, or speech difficulties.
