The nurse is caring for a client with a heart rate of 48. His blood pressure is 120/80. Which finding will help the nurse determine the cause of the client's bradycardia?

The client has a fever.

The client has possible hemorrhage or bleeding.

The client has chronic obstructive pulmonary disease (COPD).

The client has calcium channel blocker medicate prescribed.

Answer and Explanation

The Correct Answer is D

A.   Fever can cause tachycardia (increased heart rate) rather than bradycardia. It is not typically associated with slowing of the heart rate unless there are other complicating factors such as severe infection or medication side effects.
B.   Significant blood loss can lead to hypovolemia (low blood volume), which can result in bradycardia as a compensatory mechanism to maintain blood pressure. However, the blood pressure in this scenario is

normal (120/80), which makes severe hemorrhage less likely unless compensated by fluid resuscitation or other factors.
C.   COPD can cause chronic hypoxia and respiratory acidosis, which can lead to chronic respiratory compensation and potentially bradycardia. However, COPD alone is less likely to cause bradycardia in the absence of severe exacerbation or other complicating factors.
D.   Calcium channel blockers (CCBs) are medications commonly prescribed for conditions such as hypertension, angina, and arrhythmias. They work by blocking calcium channels in cardiac and smooth muscle cells, resulting in decreased heart rate and vasodilation. Bradycardia is a known side effect of CCBs, especially when taken in excess or in combination with other medications that affect heart rate.

Correct Answer is D

Explanation

A. Respiratory alkalosis is characterized by a high pH (alkaline) and a low PaCO2 (<35 mm Hg). The ABG results provided show a pH of 7.3 (which is acidic) and a PaCO2 of 50 mm Hg (which is elevated). Therefore, these results do not indicate respiratory alkalosis.
B. Metabolic acidosis is characterized by a low pH (<7.35) and a decreased bicarbonate (HCO3-). The ABG results show a pH of 7.3 (acidic), which aligns with metabolic acidosis. However, the PaCO2 of 50 mm Hg is elevated, which typically indicates respiratory compensation for the metabolic acidosis.
C. Metabolic alkalosis is characterized by a high pH and an elevated bicarbonate (HCO3-). The ABG results show a pH of 7.3 (acidic), which does not suggest metabolic alkalosis.
D. Respiratory acidosis is characterized by a low pH and an elevated PaCO2 (>45 mm Hg). The ABG results provided show a pH of 7.3 (acidic) and a PaCO2 of 50 mm Hg (elevated). These findings are consistent with respiratory acidosis, where the elevated PaCO2 indicates retention of carbon dioxide, leading to acidosis.

A. "My tongue is red and beefy." B. "My vision seems blurry." C. "I am gaining weight." D. "I am constipated."

Correct Answer is B

Explanation

A. This statement suggests symptoms of vitamin B12 deficiency or glossitis, which are not typical signs of digoxin toxicity. Therefore, it is unlikely to indicate digoxin toxicity.
B. Blurred vision is a common neurological symptom of digoxin toxicity. It occurs due to disturbances in visual acuity and color vision, which can manifest as seeing halos around lights or difficulty focusing. Therefore, this statement is indicative of potential digoxin toxicity.
C. Weight gain can occur due to fluid retention, which is a symptom of heart failure rather than digoxin toxicity. Digoxin toxicity typically presents with neurological and gastrointestinal symptoms rather than weight gain.
D. Constipation is not typically associated with digoxin toxicity. Gastrointestinal symptoms such as nausea, vomiting, and anorexia are more common with digoxin toxicity, but constipation is not a specific indicator.
