A nurse is reviewing the ABG values of a client who has pneumonia. Which of the following findings indicates the client is developing respiratory acidosis?
PaO2 85 mmHg
pH 7.47
HCO3 25 mEq/L
PaCO2 55 mmHg
The Correct Answer is D
Choice A reason: PaO2 85 mmHg is within the normal range of 80 to 100 mmHg and does not indicate any hypoxemia or oxygen deficiency.
Choice B reason: pH 7.47 is within the normal range of 7.35 to 7.45 and does not indicate any acid-base imbalance.
Choice C reason: HCO3 25 mEq/L is within the normal range of 22 to 26 mEq/L and does not indicate any metabolic disturbance.
Choice D reason: PaCO2 55 mmHg is above the normal range of 35 to 45 mmHg and indicates respiratory acidosis, which is a condition where the lungs cannot eliminate enough carbon dioxide and the blood becomes too acidic. This can be caused by pneumonia, which can impair gas exchange and ventilation.

Correct Answer is B
Explanation
Choice A reason: Having a bologna sandwich is not a good choice for a client who has hypertension, as bologna is a processed meat that contains high amounts of sodium and saturated fat, which can raise blood pressure and cholesterol levels.
Choice B reason: Seasoning food with vinegar is a good choice for a client who has hypertension, as vinegar is a low-sodium condiment that can add flavor and acidity to food without increasing blood pressure.
Choice C reason: Seasoning food with ketchup is not a good choice for a client who has hypertension, as ketchup is a high-sodium condiment that can increase blood pressure and fluid retention.
Choice D reason: Having canned soup is not a good choice for a client who has hypertension, as canned soup is a high-sodium food that can increase blood pressure and fluid retention. The client should choose low-sodium or homemade soup instead.
Correct Answer is C
Explanation
Choice A reason: Doing testicular self-exam every 6 months without fail is not an adequate frequency, as it can delay the detection of any changes or abnormalities in the testes that may indicate cancer or other conditions. Men should perform testicular self-exam monthly, preferably after a warm bath or shower.
Choice B reason: The flu shot received last year will not last for 2 years, as it only provides protection against specific strains of influenza virus that may change from year to year. People should get a flu shot annually, preferably before the flu season starts.
Choice C reason: Examining breasts a week after each menstrual period is an optimal time, as breasts are less likely to be swollen, tender, or lumpy due to hormonal fluctuations. Women should perform breast self-exam monthly, preferably at the same time each month.
Choice D reason: Getting a hepatitis B vaccine on a yearly basis is not necessary, as it only requires three doses at 0, 1, and 6 months to provide lifelong immunity against hepatitis B virus infection. People who are at high risk of exposure to hepatitis B virus should get tested for antibodies before receiving the vaccine series.
