A nurse is preparing to infuse a 250-mL unit of packed RBCs over 2 hours. The drop factor of the manual IV tubing is 15 gtts/mL. The nurse should adjust the flow rate to deliver how many drops per minute?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason:

Urinary hesitancy, while concerning, is not typically an immediate threat to the client’s health. It can indicate underlying issues such as benign prostatic hyperplasia (BPH) or urinary tract infections, which require medical attention but are generally not life-threatening. Addressing urinary hesitancy is important, but it does not take precedence over more acute conditions.

Choice B reason:

Swollen gums can be a sign of poor oral hygiene, gingivitis, or other dental issues. While important to address, swollen gums are not usually an immediate threat to the client’s overall health. Dental issues can lead to complications if left untreated, but they do not typically require urgent intervention.

Choice C reason:

Dysphagia, or difficulty swallowing, is a priority because it can lead to serious complications such as aspiration pneumonia, malnutrition, and dehydration. Aspiration pneumonia occurs when food or liquid enters the lungs, leading to infection. Dysphagia can also cause significant discomfort and impact the client’s ability to eat and drink adequately, making it a critical issue to address promptly.

Choice D reason:

Pruritus, or itching, can be a symptom of various conditions, including allergies, skin disorders, or systemic diseases such as liver or kidney problems. While pruritus can be very uncomfortable and impact the client’s quality of life, it is not typically an immediate threat to health. It requires assessment and management but is not as urgent as dysphagia.

Choice A reason:

The arterial blood gas (ABG) values of pH 7.26, HCO₃ 14, and PaCO₂ 30 indicate metabolic acidosis with partial respiratory compensation. Acute kidney injury (AKI) often leads to metabolic acidosis due to the kidneys’ inability to excrete acid and reabsorb bicarbonate. The low pH indicates acidosis, the low bicarbonate (HCO₃) reflects metabolic acidosis, and the low PaCO₂ shows that the respiratory system is trying to compensate by blowing off CO₂.

Choice B reason:

The ABG values of pH 7.49, HCO₃ 30, and PaCO₂ 40 indicate metabolic alkalosis. This condition is characterized by an elevated pH and bicarbonate level. Metabolic alkalosis is not typically associated with acute kidney injury. Instead, it can result from excessive bicarbonate intake, loss of gastric acid (e.g., vomiting), or diuretic use.

Choice C reason:

The ABG values of pH 7.26, HCO₃ 24, and PaCO₂ 46 suggest respiratory acidosis. The low pH indicates acidosis, but the normal bicarbonate level and elevated PaCO₂ point to a respiratory cause rather than a metabolic one. Respiratory acidosis occurs when the lungs cannot remove enough CO₂, leading to its accumulation. This is not a typical presentation of AKI.

Choice D reason:

The ABG values of pH 7.49, HCO₃ 24, and PaCO₂ 30 indicate respiratory alkalosis. The high pH and low PaCO₂ suggest that the patient is hyperventilating, leading to excessive CO₂ loss. This condition is not commonly associated with acute kidney injury, which more frequently causes metabolic acidosis.
