A nurse is caring for a client who has pneumonia with dyspnea. The client's ABG results are pH 7.30, PaCO2 50 mm Hg, HCO3 26 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?
Metabolic acidosis
Respiratory acidosis
Respiratory alkalosis
Metabolic alkalosis
The Correct Answer is B
This ABG result indicates that the client has an excess of carbon dioxide (CO2) due to hypoventilation.
A. "Metabolic acidosis" is an incorrect answer because the pH is low and the HCO3 is within normal range.
C. "Respiratory alkalosis" is an incorrect answer because the pH is low and the PaCO2 is elevated.
D. "Metabolic alkalosis" is an incorrect answer because the HCO3 is within normal range, and the pH is low.
Explanation: The ABG result shows a low pH, elevated PaCO2, and normal HCO3, indicating respiratory acidosis. This condition can be caused by conditions that affect breathing, such as pneumonia, asthma, or chronic obstructive pulmonary disease (COPD).

Correct Answer is D
Explanation
Opioid toxicity causes central nervous system and respiratory depression, which can lead to low blood pressure or hypotension.
Choice A. Diaphoresis is not correct because opioid toxicity does not cause excessive sweating. Diaphoresis can be a sign of opioid withdrawal or other conditions.
Choice B. Pupillary dilation is not correct because opioid toxicity causes miosis or pinpoint pupils due to the stimulation of the parasympathetic nervous system .
Choice C. Chest pain is not correct because opioid toxicity does not cause chest pain. Chest pain can be a sign of cardiac ischemia, pulmonary embolism, or other serious conditions.
Correct Answer is C
Explanation
The client should wear a mask during transport to prevent the spread of infectious droplets. The nurse should wear appropriate personal protective equipment (PPE) based on the precautions required for the specific client, which in this case would be a mask. The nurse does not need to wear a gown as droplet precautions do not require the use of a gown during transport.
The correct answer is choice C, the client should wear a mask during transport.
Choice A rationale:
The client wearing a gown during transport is not typically necessary for droplet precautions unless there is a risk of the gown becoming contaminated with infectious material. Gowns are primarily used to protect the healthcare worker or other patients if there is direct contact with the patient.
Choice B rationale:
While the nurse should wear a mask if they will be within close proximity to the client, the primary concern in droplet precautions is to prevent the spread of infection from the client, who is the source of the droplets.
Choice C rationale:
The client should wear a mask during transport to contain respiratory secretions and minimize the risk of droplet spread, as droplets can be disseminated by coughing, sneezing, or talking. This is a key component of source control in droplet precautions.
Choice D rationale:
Similar to choice A, the nurse wearing a gown during transport is not a standard requirement for droplet precautions unless there is anticipated contact with the patient or their environment that might result in contamination.
In summary, the primary goal of droplet precautions is to prevent the spread of infections through large respiratory droplets that are expelled by the client. Therefore, having the client wear a mask is the most effective measure among the options provided to reduce the risk of transmission during transport.
