A nurse is providing teaching to a client about recognizing manifestations of an impending cardiac arrest. Which of the following manifestations should the nurse include in the teaching?
Muscular aches in the leg
Profound fatigue
Severe headache
Ringing in the ears
The Correct Answer is B
A. Muscular aches in the leg: Muscular aches in the leg are not typically indicative of an impending cardiac arrest. While leg pain or cramping can be associated with peripheral vascular disease or venous insufficiency, they are not specific signs of cardiac arrest.
B. Profound fatigue: Profound fatigue can be a warning sign of an impending cardiac arrest. Fatigue or weakness can result from inadequate blood flow to the heart muscle, which may occur prior to a cardiac event. Additionally, systemic effects of cardiovascular compromise can lead to generalized weakness and fatigue.
C. Severe headache: While severe headache can be associated with conditions such as hypertension or intracranial bleeding, it is not a typical manifestation of an impending cardiac arrest. Headaches may occur as a result of stress or anxiety related to the cardiac event, but they are not a direct warning sign of impending cardiac arrest.
D. Ringing in the ears: Ringing in the ears, also known as tinnitus, is not typically associated with an impending cardiac arrest. Tinnitus can result from various factors such as noise exposure, ear infections, or certain medications, but it is not considered a warning sign of impending cardiac arrest.

Correct Answer is A
Explanation
A. A decrease in systolic blood pressure greater than 10 mm Hg during inspiration: Pulsus paradoxus is an exaggerated decrease in systolic blood pressure during inspiration. Normally, there is a slight decrease in systolic blood pressure during inspiration due to increased intrathoracic pressure and decreased venous return to the heart. However, in conditions such as cardiac tamponade or severe asthma exacerbations, the decrease in systolic blood pressure during inspiration is more pronounced (>10 mm Hg), indicating impaired cardiac output and decreased left ventricular filling during inspiration.
B. A decrease in heart rate greater than 10/min when lying down: This finding is not indicative of pulsus paradoxus. Pulsus paradoxus primarily refers to changes in systolic blood pressure during inspiration rather than alterations in heart rate when lying down.
C. An increase in diastolic blood pressure greater than 10 mm Hg during inspiration: This finding is not indicative of pulsus paradoxus. Pulsus paradoxus is characterized by an exaggerated decrease in systolic blood pressure during inspiration, not changes in diastolic blood pressure.
D. An increase in heart rate greater than 20/min when standing: This finding is not indicative of pulsus paradoxus. Pulsus paradoxus primarily refers to changes in systolic blood pressure during inspiration rather than alterations in heart rate when standing.
Correct Answer is ["A","B","C","D"]
Explanation
All of the following should be included in the teaching:
A. Living a sedentary lifestyle: Sedentary behavior, characterized by physical inactivity, is a risk factor for various cardiovascular conditions, including atrial fibrillation. Regular exercise is important for maintaining heart health and reducing the risk of atrial fibrillation.
B. Family history of atrial fibrillation: A family history of atrial fibrillation increases an individual's risk of developing the condition. Genetic factors play a role in predisposing individuals to atrial fibrillation, and having a close relative with the condition can elevate one's risk.
C. History of thyroid disease: Thyroid disorders, particularly hyperthyroidism (overactive thyroid), are associated with an increased risk of atrial fibrillation. Thyroid hormones influence heart rate and rhythm, and imbalances can predispose individuals to atrial fibrillation.
D. Recent influenza infection: Infections, particularly respiratory infections such as influenza, can trigger episodes of atrial fibrillation in susceptible individuals. The inflammatory response and physiological stress associated with infections can disrupt normal heart rhythm and precipitate atrial fibrillation episodes.
