The nurse interviews a client admitted for an outpatient procedure and enters a long list of home medications into the medical record.

The nurse observes several medications that are prescribed for the same indications.

Which instruction is best for the nurse to communicate to the client regarding the multiple prescriptions?

Choice A rationale:

An elevated serum creatinine level can indicate kidney dysfunction or damage, which can be a possible adverse effect of amoxicillin-clavulanate. The kidneys are responsible for excreting the medication, and elevated creatinine levels suggest impaired renal function.

Choice B rationale:

An elevated serum alanine aminotransferase (ALT) level is indicative of liver dysfunction or damage. Amoxicillin-clavulanate can sometimes cause hepatotoxicity as a side effect, and elevated ALT levels may suggest this adverse effect.

Choice D rationale:

An elevated white blood cell count (leukocytosis) can be a possible adverse effect of amoxicillin-clavulanate, indicating an increase in the body's immune response. This could be due to an allergic reaction or other adverse reactions to the medication.

Choice C rationale:

An elevated serum potassium level is not typically associated with amoxicillin-clavulanate use. This finding is more likely related to other factors such as kidney dysfunction or certain medications like potassium-sparing diuretics.

Choice E rationale:

An elevated platelet count is not typically associated with amoxicillin-clavulanate use. This finding is more likely related to other factors, such as a bone marrow disorder or inflammation.

Choice A rationale:

Supplemental oxygen is given to the patient to prevent hypoxia and tissue damage due to pneumonia. Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing. Hypoxia occurs when the body or a region of the body is deprived of adequate oxygen supply at the tissue level. It can cause serious damage to your heart, brain, and other organs. Hence, supplemental oxygen is administered to ensure that the patient’s tissues receive adequate oxygen.

Choice B rationale:

While supplemental oxygen can indirectly help lower blood pressure by improving oxygen supply and reducing strain on the heart, it is not primarily used for this purpose. Enalapril, which the patient is already taking, is an angiotensin-converting enzyme (ACE) inhibitor that is commonly used to lower blood pressure and reduce the workload of the heart.

Choice C rationale:

Supplemental oxygen does increase the oxygen saturation and improve respiratory function. However, this is a more general rationale for providing supplemental oxygen and not specific to this patient’s condition of pneumonia.

Choice D rationale:

Supplemental oxygen does not directly dilate the bronchioles or decrease inflammation in the lungs. Medications such as bronchodilators and corticosteroids are typically used for these purposes. In this case, supplemental oxygen is being used to prevent hypoxia and tissue damage due to pneumonia.
