When teaching about methyldopa, it is important for the patient to know that it

Correct Answer: C

Rationale: In the context of teaching about methyldopa to patients, it is crucial for them to understand that option C) may produce drowsiness initially is the correct answer. Methyldopa is an antihypertensive medication that acts centrally to reduce blood pressure. One of the common side effects of methyldopa is drowsiness, especially when initiating treatment. Educating patients about this potential side effect is important for them to be aware and to prevent any unnecessary concerns or alarm. Option A) decreases cardiac output is incorrect because methyldopa primarily acts on the central nervous system to reduce blood pressure and does not directly impact cardiac output. Option B) may produce mental confusion is incorrect as mental confusion is not a common side effect associated with methyldopa use. Option D) blocks the release of norepinephrine is incorrect as methyldopa works by being converted into alpha-methyl norepinephrine, which then acts in the brain to decrease sympathetic outflow, thereby lowering blood pressure. In an educational context, teaching patients about the potential side effects of medications like methyldopa empowers them to recognize and manage these effects effectively. It also fosters a sense of autonomy and responsibility in their own healthcare management. This knowledge enables patients to make informed decisions and seek timely medical advice if needed.

Correct Answer: A

Rationale: In this scenario, the correct answer is option A) 1-lb weight gain in 2 days. This is a crucial symptom that clients taking diuretics for chronic congestive heart failure need to report promptly. This rapid weight gain can indicate fluid retention, a sign that the heart failure is worsening, and immediate medical intervention may be necessary. Option B) Seeing yellow hazes around bright lights is not directly related to the management of congestive heart failure or diuretic therapy. This symptom could be indicative of other health issues but is not a typical concern for clients in this specific context. Option C) Change in the heart rate is a common symptom in heart-related conditions, but for clients taking diuretics for heart failure, changes in heart rate may not always be a primary indicator of worsening condition compared to sudden weight gain. Option D) Change in activity tolerance is a general symptom that can be seen in various health conditions. While it is important for clients with heart failure to monitor their activity tolerance, sudden weight gain is a more specific and critical indicator that requires immediate attention in this context. Educational context: It is essential for healthcare providers to educate clients with chronic congestive heart failure about the importance of monitoring their weight regularly, as it can be an early sign of fluid retention and worsening heart failure. Recognizing and reporting such changes promptly can help prevent complications and improve outcomes for individuals with heart failure.

Correct Answer: C

Rationale: In third-degree atrioventricular block (complete heart block), there is a complete dissociation between the atria and ventricles, leading to an independent rhythm of both. The correct answer is C) A slow heart rate because in this condition, the ventricles are activated by an escape rhythm originating from a lower pacemaker site, resulting in a slower heart rate. Option A) A highly variable PR interval is incorrect because in third-degree AV block, there is no relationship between the P waves and QRS complexes, so PR intervals are not applicable. Option B) Regular PP intervals are incorrect because PP intervals refer to the atrial activity, which may be regular in this condition but do not reflect the lack of conduction to the ventricles. Option D) Regular RR intervals are incorrect because RR intervals measure the ventricular rate, and in third-degree AV block, the ventricular rate is typically slower and irregular due to the escape rhythm. Educationally, understanding the different degrees of heart block is crucial for healthcare professionals as it impacts patient management and treatment decisions. Recognizing the characteristic features of each degree of heart block, like the specific ECG findings in third-degree AV block, is essential for providing appropriate care to patients with cardiac conduction abnormalities.

Correct Answer: C

Rationale: In Mrs. Jones' discharge teaching with a permanent pacemaker, covering the point that she can return to the degree of sexual activity that is desired and tolerable for her is crucial. This information is important as it addresses a common concern among patients with pacemakers and promotes a holistic approach to her quality of life post-implantation. Educating Mrs. Jones about resuming sexual activity helps address her emotional and psychological well-being, enhancing her overall recovery process. Option A is incorrect because having a pacemaker does not necessarily mean one cannot get pregnant; however, it is important to consult with her healthcare provider. Option B is incorrect as regular exercise is generally encouraged for patients with pacemakers to maintain cardiovascular health. Option D is incorrect as regular follow-up visits with her physician are essential to monitor the pacemaker's function and her overall cardiac health. By explaining the importance of sexual activity in the context of pacemaker management, healthcare providers can empower patients like Mrs. Jones to make informed decisions about their lifestyle and well-being, fostering a collaborative and patient-centered approach to care.
