A patient recently prescribed a calcium channel blocker for the treatment of hypertension is experiencing dizziness when rising to a standing position. Which action will the nurse take?
Instruct the patient to monitor weight daily.
Inform the patient to discontinue the medication.
Advise the patient to increase dietary sodium.
Encourage the patient to sit down if feeling faint.
The Correct Answer is D
Choice A reason: This is not the action that the nurse should take. Instructing the patient to monitor weight daily is not relevant to the patient's dizziness. Weight monitoring is more useful for patients with fluid retention or heart failure, which are not caused by calcium channel blockers.
Choice B reason: This is not the action that the nurse should take. Informing the patient to discontinue the medication is not appropriate, as this can cause rebound hypertension and other complications. The patient should not stop taking the medication without consulting their health care provider.
Choice C reason: This is not the action that the nurse should take. Advising the patient to increase dietary sodium is not helpful, as this can worsen the hypertension and increase the risk of cardiovascular events. The patient should follow a low-sodium diet and avoid salt substitutes that contain potassium.
Choice D reason: This is the action that the nurse should take. Encouraging the patient to sit down if feeling faint is a simple and effective way to prevent falls and injuries. Dizziness is a common side effect of calcium channel blockers, especially when the patient changes position or stands up quickly. This is due to the orthostatic hypotension (a drop in blood pressure when standing up) caused by the vasodilation effect of the medication. However, this side effect is usually mild and transient, and can be prevented by rising slowly from a sitting or lying position, drinking plenty of fluids, and avoiding alcohol.

Correct Answer is B
Explanation
Choice A reason: Infection in the blood is not empyema. It is sepsis, which is a life-threatening condition that occurs when the body's response to infection causes tissue damage, organ failure, or death.
Choice B reason: Infection in the pleural space is empyema. It is a collection of pus in the space between the lungs and the chest wall, usually caused by a bacterial infection that spreads from the lungs or the chest cavity.
Choice C reason: Exudative bronchitis is not empyema. It is a type of bronchitis that involves inflammation and excess mucus production in the bronchi, the airways that carry air to the lungs.
Choice D reason: Infection localized in the lung is not empyema. It is pneumonia, which is an inflammation of the lung tissue, usually caused by a viral or bacterial infection that affects the air sacs or the interstitial tissue.
Correct Answer is D
Explanation
Choice A reason: This is not the cause of pulmonary symptoms in left heart failure. Decreased cardiac output is a consequence of left heart failure, which affects the perfusion of vital organs and tissues.
Choice B reason: This is not the cause of pulmonary symptoms in left heart failure. Bronchoconstriction is a feature of asthma and chronic obstructive pulmonary disease (COPD), which affect the airways and cause wheezes and shortness of breath.
Choice C reason: This is not the cause of pulmonary symptoms in left heart failure. Inflammatory pulmonary edema is a type of non-cardiogenic pulmonary edema, which occurs when the alveolar-capillary membrane is damaged by an inflammatory process, such as pneumonia or sepsis.
Choice D reason: This is the correct cause of pulmonary symptoms in left heart failure. Pulmonary vascular congestion is a result of increased pressure in the pulmonary circulation, which occurs when the left ventricle fails to pump blood effectively to the aorta and the rest of the body. This causes fluid to leak into the alveoli and interstitial spaces, leading to cough, dyspnea, crackles, and pink frothy sputum.
