1. A healthcare professional is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the healthcare professional expect?

Correct answer: B

Rationale: In respiratory acidosis, the primary disturbance is an increase in PaCO2 levels above the normal range of 35-45 mm Hg. Option B, PaCO2 50 mm Hg, indicates an elevated partial pressure of carbon dioxide, which is consistent with respiratory acidosis. Options A, C, and D are not directly indicative of respiratory acidosis. HCO3- (Option A) is more related to metabolic acidosis or alkalosis, pH (Option C) is within the normal range indicating no acid-base imbalance, and potassium (Option D) levels are not specific to respiratory acidosis.

2. A nurse on the postpartum unit is caring for a group of clients with an assistive personnel (AP). Which of the following tasks should the nurse plan to delegate to the AP?

Correct answer: A

Rationale: Delegating the task of providing a sitz bath to a client with a fourth-degree laceration and who is 2 days postpartum to the assistive personnel (AP) is appropriate. This task involves assisting the client with personal hygiene and comfort measures that can be safely performed by the AP under the supervision and direction of the nurse. Tasks like observing redness on the breast, monitoring vital signs during admission for gestational hypertension, and changing perineal pads may require a higher level of assessment and nursing judgment, making them more appropriate for the nurse to perform.

3. A client is being assessed for postpartum infection. Which of the following findings should indicate to the healthcare provider that the client requires further evaluation for endometritis?

Correct answer: B

Rationale: Pelvic pain is a common symptom of endometritis, which is an infection of the uterine lining. It is an important finding that warrants further evaluation. Localized area of breast tenderness may indicate mastitis, vaginal discharge with a foul odor could suggest a vaginal infection, and hematuria points towards a urinary tract issue, but they are not specific to endometritis.

4. A newborn's mother is positive for the hepatitis B surface antigen. Which of the following should the infant receive?

Correct answer: C

Rationale: In the scenario where a newborn's mother is positive for hepatitis B surface antigen, the infant should receive both hepatitis B immune globulin and hepatitis B vaccine within 12 hours of birth. This is crucial to provide passive and active immunity against the Hepatitis B virus. Hepatitis B immune globulin provides immediate protection by giving passive immunity, while the vaccine stimulates active immunity in the infant. Administering both within 12 hours of birth is important to prevent vertical transmission of the virus.

5. When reviewing the arterial blood gas values for a client, a nurse notes a pH of 7.32, PaCO2 of 48 mm Hg, and HCO3 of 23 mEq/L. What does this indicate about the acid-base balance?

Correct answer: A

Rationale: The given values suggest respiratory acidosis. In respiratory acidosis, the pH is low (<7.35), PaCO2 is high (>45 mm Hg), and the HCO3 is normal or slightly elevated. In this scenario, the low pH (7.32) and high PaCO2 (48 mm Hg) indicate respiratory acidosis, where there is an excess of carbon dioxide in the blood, leading to acidification of the body fluids.
