A nurse is reviewing the laboratory results of a client who was an unrestrained passenger in a motor-vehicle crash. The ABG results are as follows: pH 7.32, HCO3 24 mEq/L, PaCO2 48 mm Hg. The nurse should identify the client is experiencing which of the following acid-base imbalances?
Respiratory acidosis
Metabolic acidosis
Respiratory alkalosis
Metabolic alkalosis
The Correct Answer is A
A) Respiratory acidosis: This condition is indicated by a low pH (7.32) and an elevated PaCO2 (48 mm Hg), while HCO3 remains normal (24 mEq/L). Respiratory acidosis occurs when there is an accumulation of carbon dioxide in the blood, usually due to hypoventilation or impaired gas exchange in the lungs.
B) Metabolic acidosis: Metabolic acidosis is characterized by a low pH and a decreased HCO3 level. In this scenario, the HCO3 level is normal, ruling out metabolic acidosis.
C) Respiratory alkalosis: Respiratory alkalosis is indicated by a high pH and a decreased PaCO2. In this case, the pH is low, and the PaCO2 is elevated, which contradicts the characteristics of respiratory alkalosis.
D) Metabolic alkalosis: Metabolic alkalosis would show a high pH and an elevated HCO3 level. Since the pH is low and the HCO3 is normal, this condition does not fit the criteria for metabolic alkalosis.

Correct Answer is A
Explanation
A) Lymphocytes 30%:
Lymphocyte levels are typically elevated during the acute phase of mononucleosis as the body fights the Epstein-Barr virus. A level of 30% indicates that the lymphocyte count is returning to a more normal range, which suggests the client is recovering from the infection.
B) RBC 4.4:
The red blood cell count is not directly indicative of recovery from mononucleosis. While it provides information about the client's overall hematologic status, it does not specifically reflect the status of the viral infection.
C) Hgb 14 g/dL:
Hemoglobin levels can provide information about the client's oxygen-carrying capacity but do not specifically indicate recovery from mononucleosis. Normal hemoglobin levels are reassuring but not directly related to the viral infection's resolution.
D) Hct 42%:
Hematocrit levels, like hemoglobin, offer information about the client's blood composition but do not directly indicate recovery from mononucleosis. While normal hematocrit levels are desirable, they are not specific to the recovery status of the viral illness.
Correct Answer is A
Explanation
A) Rotating the earmold forward when inserting the hearing aid is a correct technique. This ensures a proper fit and helps to position the hearing aid comfortably in the ear canal, which can enhance the effectiveness and comfort of the device.
B) Cleaning the hearing aid with alcohol swabs can damage the delicate components of the device. Instead, hearing aids should be cleaned with a dry cloth or a soft brush specifically designed for this purpose to avoid damaging the hearing aid.
C) Turning the hearing aid on before inserting it may result in feedback or a whistling sound. It's usually recommended to insert the hearing aid first and then turn it on to avoid any discomfort or unwanted noise.
D) If the hearing aid whistles, it is not typically related to the battery. Whistling is often caused by improper fit, earwax buildup, or feedback issues. Changing the battery is unlikely to resolve the whistling problem and is not the recommended solution.
