Question

Which of the following is an untoward effect of angiotensin-converting agents that should be reported to the doctor? A. Postural dizziness B. Occasional nausea C. $1+$ petal edema D. Persistent hacking cough

Short answer

Answer: Persistent Hacking Cough

Step-by-step solution

Understanding Angiotensin-Converting Agents (ACE inhibitors)

Angiotensin-converting enzyme inhibitors are medications used to treat conditions like hypertension or heart failure. They work by blocking the conversion of angiotensin I to angiotensin II, which is a substance that causes constriction of blood vessels and stimulates the release of aldosterone. This results in lowered blood pressure and improved heart function.

Evaluating Option A: Postural Dizziness

Postural dizziness, also known as orthostatic hypotension, is a drop in blood pressure that occurs upon standing up. This can be caused by several medications, including ACE inhibitors. This is a potentially serious side effect that should be reported to the doctor.

Evaluating Option B: Occasional Nausea

Occasional nausea might occur with the use of ACE inhibitors, but it's usually mild and goes away on its own. While it's important to inform the doctor if it becomes persistent or more severe, occasional nausea is not a pivotal concern.

Evaluating Option C: $1+$ Petal Edema

Edema, or swelling in the legs, ankles, or feet, may be a side effect of ACE inhibitors, but it is less common. A low degree edema ($1+$) might not necessarily require immediate reporting to the doctor, but it should be monitored closely.

Evaluating Option D: Persistent Hacking Cough

A persistent hacking cough is a well-known side effect associated with ACE inhibitors, affecting a significant number of people who take these medications. The cough can be irritating and disruptive, but it's non-productive (no mucus). Persistent hacking cough should be reported to the doctor, as it might indicate that the medication needs to be adjusted or an alternative treatment should be considered.

Conclusion

Based on our evaluation, the most concerning untoward effect of angiotensin-converting agents that should be reported to the doctor among the given options is Option D: Persistent Hacking Cough.

Key concepts

Hypertension Medication Side Effects

When managing hypertension, also known as high blood pressure, medications are often prescribed to help control the condition. Angiotensin-converting enzyme (ACE) inhibitors are commonly used for this purpose. While these medications are effective, they can come with a range of side effects.

Common Side Effects

Patients may experience side effects such as postural dizziness, or orthostatic hypotension, which can be a sign of overly lowered blood pressure. It's important for healthcare providers to educate patients about the signs of this, as it might require medical attention.

Less Common Side Effects

Other side effects might include swelling (edema), which while less common, should be monitored carefully. If a patient exhibits severe or worsening symptoms, they may need a medication adjustment.

Understanding and managing side effects not only ensures the safety and comfort of the patient but also helps in maintaining consistency in medication adherence, improving the overall effectiveness of hypertension treatment.

ACE Inhibitor Cough

One of the more unique and notable side effects of ACE inhibitors is a persistent hacking cough. This cough is typically dry and non-productive, meaning it doesn't produce mucus.

Why Does It Occur?

The mechanism behind this cough lies in the effects of ACE inhibitors on the respiratory system. By inhibiting the enzyme, these medications also accumulate substances like bradykinin in the lungs, leading to irritation and cough.

Distinguishing Features

Characteristically, the cough is relentless and tends to get worse at night, often disrupting sleep. Because of its impact on quality of life, patients must convey this side effect to their healthcare provider promptly.

A change in medication might be necessary, and healthcare providers have alternatives, such as angiotensin receptor blockers (ARBs), which do not commonly produce cough as a side effect.

Pharmacology Nursing Education

Pharmacology is a pillar of nursing education, equipping future nurses with the knowledge necessary to administer medications safely and effectively. A solid understanding of drugs like ACE inhibitors is crucial due to their widespread use and potential side effects.

Teaching the Basics

Educators should focus on the drug's mechanism of action, therapeutic uses, and the spectrum of possible side effects, using real-world scenarios to illustrate these points.

Implications for Practice

Equally important is the training on monitoring patient responses and the proper actions when side effects occur. This preparation is vital for nurses to make informed decisions in clinical settings and to manage patient education and health outcomes effectively.

NCLEX-RN Exam Preparation

The National Council Licensure Examination for Registered Nurses (NCLEX-RN) is a milestone for nursing students. It tests the knowledge and skills necessary to practice nursing safely and effectively, including pharmacology.

Reviewing Key Drug Classes

It's essential for students to be familiar with medication classes like ACE inhibitors, understanding their use cases and side effects. Questions regarding these medications often extend beyond straightforward recognition and require critical thinking regarding patient safety and drug interactions.

Preparation Strategies

Students should engage in comprehensive study sessions, practical applications, and practice questions that reflect the exam format. This will help ensure that they are well-prepared for any pharmacology-related questions on the NCLEX-RN.
