A nurse is providing discharge instructions to a client who has GERD. Which of the following statements by the client demonstrates an understanding of the teaching?

I should take my medicine with orange juice.

A bedtime snack will prevent heartburn.

I will lie down after meals.

I will limit activities that require bending at the waist.

Answer and Explanation

The Correct Answer is D

Choice A Reason:

Taking medicine with orange juice is not recommended for clients with GERD. Citrus juices, including orange juice, are highly acidic and can exacerbate GERD symptoms by increasing stomach acidity and causing reflux.

Choice B Reason:

A bedtime snack is likely to worsen heartburn rather than prevent it. Eating close to bedtime can increase the likelihood of acid reflux during the night, as lying down soon after eating can cause stomach contents to flow back into the esophagus.

Choice C Reason:

Lying down after meals is not advisable for clients with GERD. It is recommended to remain upright for at least 2-3 hours after eating to help prevent acid reflux. Lying down can increase the risk of stomach acid flowing back into the esophagus.

Choice D Reason:

Limiting activities that require bending at the waist is a good practice for managing GERD. Bending over can increase abdominal pressure and promote acid reflux. Instead, clients should try to bend at the knees or avoid such activities when possible.

Correct Answer is A

Explanation

Choice A Reason:

A distended, board-like abdomen is a critical finding that can indicate peritonitis, a severe complication of appendicitis. Peritonitis occurs when the appendix ruptures, leading to infection spreading throughout the abdominal cavity. This condition requires immediate medical intervention to prevent further complications and potential sepsis.

Choice B Reason:

A WBC count of 15,000/mm³ is elevated and suggests an infection, which is common in appendicitis. However, it is not as immediately critical as signs of peritonitis. Elevated WBC counts are expected in cases of appendicitis but do not necessarily indicate a life-threatening emergency.

Choice C Reason:

Rebound tenderness over McBurney’s point is a classic sign of appendicitis and indicates localized inflammation. While it is an important diagnostic sign, it does not require immediate reporting compared to signs of peritonitis.

Choice D Reason:

A temperature of 37.3°C (99.1°F) is only slightly elevated and does not indicate a severe infection or complication. Fever is a common symptom of appendicitis but is not as critical as a distended, board-like abdomen.

A. Respiratory acidosis B. Respiratory alkalosis C. Metabolic acidosis D. Metabolic alkalosis

Correct Answer is B

Explanation

Choice A Reason:

Respiratory acidosis is characterized by a low pH (below 7.35) and an elevated PaCO₂ (above 45 mm Hg). This condition occurs when there is an accumulation of carbon dioxide in the blood due to hypoventilation or impaired lung function. In this case, the client’s pH is elevated, and PaCO₂ is low, which does not align with respiratory acidosis.

Choice B Reason:

Respiratory alkalosis is indicated by a high pH (above 7.45) and a low PaCO₂ (below 35 mm Hg). This condition results from hyperventilation, which causes excessive exhalation of carbon dioxide. The client’s ABG results show a pH of 7.50 and a PaCO₂ of 29 mm Hg, consistent with respiratory alkalosis.

Choice C Reason:

Metabolic acidosis is characterized by a low pH (below 7.35) and a low HCO₃ (below 21 mEq/L). This condition occurs due to an accumulation of acids or a loss of bicarbonate in the body. The client’s pH is elevated, and HCO₃ is within the normal range, which does not indicate metabolic acidosis.

Choice D Reason:

Metabolic alkalosis is indicated by a high pH (above 7.45) and a high HCO₃ (above 28 mEq/L). This condition results from an excess of bicarbonate or a loss of acids. The client’s pH is elevated, but HCO₃ is within the normal range, which does not support a diagnosis of metabolic alkalosis.
