A client is brought into the emergency department for an overdose of morphine. The client has a respiratory rate of 5 to 8 breaths per minute. Which of the following ABG results would the nurse expect to see?
pH 7.45, PaCO2 35, HCO3 22
pH 7.25. PaCO2 61, HCO3 26
pH 7.23. PaCO2 27, HCO3 25
pH 7.54, PaCO2 59. HCO3 26
The Correct Answer is B
B. pH 7.25, PaCO2 61, HCO3 26
pH is decreased (acidosis).
PaCO2 is elevated (61 mmHg), indicating respiratory acidosis (increased CO2 retention). HCO3 is slightly elevated (26 mEq/L), compensating for the respiratory acidosis.
A. pH 7.45, PaCO2 35, HCO3 22
pH is within normal range (7.35-7.45).
PaCO2 is slightly lower than normal (35 mmHg), indicating mild respiratory alkalosis. HCO3 (bicarbonate) is within normal range (22 mEq/L).
C. pH 7.23, PaCO2 27, HCO3 25
pH is decreased (acidosis).
PaCO2 is lower than normal (27 mmHg), indicating respiratory alkalosis (which is unlikely in the context of morphine overdose with hypoventilation).
HCO3 is within normal range (25 mEq/L).
D. pH 7.54, PaCO2 59, HCO3 26
pH is increased (alkalosis).
PaCO2 is elevated (59 mmHg), indicating respiratory acidosis (consistent with hypoventilation). HCO3 is slightly elevated (26 mEq/L), compensating for the respiratory acidosis.

Correct Answer is D
Explanation
D. This is the most appropriate goal for a client experiencing diarrhea. Diarrhea is characterized by loose or watery stools, and the goal of treatment is to restore normal stool consistency. This goal focuses on improving the symptoms and resolving the underlying cause of diarrhea, whether it's due to infection, dietary factors, or other reasons.
A. "Defecating regularly" does not necessarily imply improvement in diarrhea symptoms or resolution of the underlying cause. It is vague and does not provide a clear target related to diarrhea management.
B. Increasing ingestion of fruits may be beneficial for some individuals as fruits contain fiber and fluids that can help regulate bowel movements and maintain hydration. However, certain fruits high in fiber (e.g., apples, pears) may exacerbate diarrhea in some cases. This goal should be tailored based on the individual's tolerance and specific dietary needs.
C. This goal is not appropriate for managing diarrhea. Diarrhea leads to fluid loss and dehydration, so limiting fluid intake can worsen dehydration and electrolyte imbalances. Adequate fluid intake is crucial to replace lost fluids and maintain hydration during episodes of diarrhea.
Correct Answer is D
Explanation
D. A "thready" pulse is weak and difficult to palpate. It feels like a fine thread or string under the fingertips and suggests poor cardiac output or decreased peripheral perfusion. A thready pulse is palpable but weak, indicating inadequate stroke volume with each heartbeat.
A. Hypovolemic refers to a state of decreased blood volume, which can lead to a weak and rapid pulse due to reduced blood flow through the arteries. However, it does not specifically describe the quality of the pulse that is palpable.
B. Bradycardia refers to a slow heart rate, typically below 60 beats per minute in adults. A bradycardic pulse may be slow but can still be strong or weak depending on the underlying cause. It does not specifically describe the quality of a weak but palpable pulse.
C. "Deficient" is not a commonly used term to describe the quality of a pulse. It does not provide specific information about the palpable nature or strength of the pulse.
