Which of the following patients should be monitored closely by the nurse for superior vena cava syndrome?

76-year-old man with congestive heart failure.

66-year-old woman with bronchogenic cancer.

26-year-old woman who has just delivered her first child.

6-year-old child with severe asthma.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

A 76-year-old man with congestive heart failure may experience superior vena cava syndrome (SVCS) due to the increased pressure in the superior vena cava, but SVCS is more commonly associated with malignancies that compress or invade the superior vena cava. While this patient may be at risk for SVCS, the woman with bronchogenic cancer in choice B is at higher risk.

Choice B rationale:

The correct choice. Patients with bronchogenic cancer, particularly lung cancer, are at a higher risk of developing superior vena cava syndrome (SVCS) due to tumor invasion or compression of the superior vena cava. SVCS can cause a range of symptoms, including facial and upper body swelling, dilated neck veins, and difficulty breathing.

Choice C rationale:

A 26-year-old woman who has just delivered her first child is unlikely to develop superior vena cava syndrome (SVCS) as a result of childbirth. SVCS is more commonly associated with malignancies or other factors that cause obstruction or compression of the superior vena cava.

Choice D rationale:

A 6-year-old child with severe asthma is less likely to develop SVCS compared to adults, as SVCS is primarily associated with malignancies and other conditions that lead to obstruction of the superior vena cava. While severe asthma can cause respiratory distress, it is not a typical cause of SVCS in children. .

Correct Answer is A

Explanation

Choice A rationale:

Systolic heart failure results in increased left ventricular preload. In systolic heart failure, the heart's ability to contract and eject blood effectively is impaired. This leads to decreased ejection fraction, which means that a significant amount of blood is left in the left ventricle at the end of systole. This increased volume of blood in the left ventricle during diastole is referred to as "preload.”. The increased preload is a compensatory mechanism that the heart uses to maintain cardiac output. However, over time, this increased preload can lead to symptoms of congestion and fluid overload.

Choice B rationale:

Systolic heart failure is characterized by decreased ejection fraction, not increased. Ejection fraction is a measure of the percentage of blood ejected from the left ventricle with each heartbeat. In systolic heart failure, this percentage is reduced.

Choice C rationale:

Systolic heart failure does not directly affect right ventricular preload. Right ventricular preload is more related to conditions that affect the right side of the heart, such as pulmonary hypertension.

Choice D rationale:

Systolic heart failure does not necessarily result in decreased right ventricular end-diastolic pressure. Right ventricular end-diastolic pressure can be influenced by a variety of factors, and its alteration is not a specific hallmark of systolic heart failure.

A. Lithium. B. Valproate. C. Risperidone. D. Methylphenidate.

Correct Answer is D

Explanation

Choice A rationale:

Lithium is not typically prescribed for attention-deficit hyperactivity disorder (ADHD). It's more commonly used for bipolar disorder.

Choice B rationale:

Valproate is not a first-line treatment for ADHD in school-age children. It is used for mood stabilization in conditions like bipolar disorder.

Choice C rationale:

Risperidone is an atypical antipsychotic and is not a first-line treatment for ADHD. It may be used in some cases where there are comorbid behavioral issues, but it's not the initial choice.

Choice D rationale:

Methylphenidate is a commonly prescribed medication for ADHD in school-age children. It is a central nervous system stimulant that helps improve attention and decrease impulsiveness and hyperactivity in those with ADHD.
