A nurse is caring for a client who reports having an allergy to penicillin. Which of the following manifestations indicates an allergic reaction to penicillin?

Iron supplementation with medications such as Ferrous sulfate is commonly prescribed for children with iron deficiency anemia to restore hemoglobin levels and replenish iron stores. Effective administration requires proper technique to maximize absorption and reduce adverse effects such as gastrointestinal irritation and tooth discoloration. Caregivers must understand how to administer the medication correctly and recognize expected side effects versus abnormal findings. Education focuses on improving absorption and ensuring safe, effective therapy.

Rationale:
A. “I’ll give my child the iron with milk.” This is incorrect because calcium in milk interferes with iron absorption in the gastrointestinal tract. Dairy products bind to iron and reduce its bioavailability, making the medication less effective. Iron should ideally be given with water or a source of vitamin C, such as orange juice, to enhance absorption.

B. “I’ll notify the provider if my child becomes nauseated.” This reflects a misunderstanding because mild gastrointestinal upset is a common and expected side effect of iron therapy. Nausea can often be minimized by giving the medication with a small amount of food, although absorption may slightly decrease. Severe or persistent symptoms may require adjustment, but mild nausea does not typically require provider notification.

C. “I’ll give my child the iron through a straw.” This is correct because liquid iron can stain teeth due to its dark color and metallic content. Using a straw helps minimize contact with teeth, reducing the risk of permanent discoloration. Additionally, rinsing the mouth or brushing teeth after administration further helps protect dental enamel.

D. “I’ll notify the provider if my child’s stools are tarry.” This is incorrect because dark, tarry stools are an expected and harmless side effect of oral iron therapy. This occurs due to unabsorbed iron passing through the gastrointestinal tract and is not an indication of bleeding in this context. Caregivers should be reassured that this is a normal response to treatment.

Enalapril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension and heart failure by causing vasodilation and reducing peripheral vascular resistance. One of its common early adverse effects is orthostatic hypotension, especially after the first few doses. This can lead to dizziness or syncope when changing positions quickly. Patient education focuses on preventing falls and managing blood pressure changes safely during therapy initiation.

Rationale:
A. Rising slowly from a sitting to standing position helps prevent orthostatic hypotension associated with enalapril use. The medication causes vasodilation, which can reduce venous return and blood pressure, especially when changing positions rapidly. Gradual position changes allow the cardiovascular system time to adjust and reduce the risk of syncope and falls.

B. Decreasing daily fluid intake is incorrect because adequate hydration helps maintain blood pressure and perfusion. Reducing fluids may worsen hypotension and increase the risk of dizziness or fainting. Patients on antihypertensives should maintain appropriate fluid intake unless otherwise contraindicated.

C. Withholding the medication if pulse rate is less than 60/min is not appropriate because enalapril primarily affects blood pressure, not heart rate. Pulse-based holding parameters are more relevant for beta-blockers, not ACE inhibitors. Abrupt discontinuation without provider instruction can lead to uncontrolled hypertension or worsening heart failure.

D. Increasing dietary potassium is incorrect because ACE inhibitors like enalapril can increase serum potassium levels by reducing aldosterone secretion. Excess potassium intake may lead to hyperkalemia, which can cause dangerous cardiac dysrhythmias. Patients are usually advised to monitor or limit high-potassium foods unless otherwise prescribed.
