Nursing Elites

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?

• A. HCO3- 30 mEq/L
• B. PaCO2 50 mm Hg
• C. pH 7.45
• D. Potassium 3.3 mEq/L

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 client with acute respiratory failure (ARF) may present with which of the following manifestations? (Select one that doesn't apply.)

• A. Severe dyspnea
• B. Decreased level of consciousness
• C. Headache
• D. Nausea

Correct answer: D

Rationale: In acute respiratory failure (ARF), the body is not getting enough oxygen, leading to respiratory distress. Symptoms of ARF typically include severe dyspnea (difficulty breathing), decreased level of consciousness due to hypoxia, and headache from inadequate oxygenation to the brain. Nausea is not a typical manifestation of ARF and would not be expected in this condition.

3. A client who is 4 hours postpartum following a vaginal delivery is being assessed by a nurse. Which of the following findings should the nurse identify as the priority?

• A. Saturated perineal pad in 30 minutes
• B. Deep tendon reflexes 4+
• C. Fundus at the level of the umbilicus
• D. Approximated edges of episiotomy

Correct answer: A

Rationale: In a client who is 4 hours postpartum, a saturated perineal pad within 30 minutes is a priority finding as it may indicate excessive postpartum bleeding (hemorrhage), which requires immediate intervention to prevent further complications such as hypovolemic shock. Deep tendon reflexes being 4+ is within normal limits postpartum. The fundus at the level of the umbilicus is an expected finding at this time frame, indicating proper involution of the uterus. Approximated edges of an episiotomy suggest proper healing.

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

• A. Hepatitis B immune globulin at 1 week followed by hepatitis B vaccine monthly for 6 months
• B. Hepatitis B vaccine monthly until the newborn tests negative for the hepatitis B surface antigen
• C. Hepatitis B immune globulin and hepatitis B vaccine within 12 hr of birth
• D. Hepatitis B vaccine at 24 hr followed by hepatitis B immune globulin every 12 hr for 3 days

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. A healthcare provider is preparing to administer an injection of Rho (D) immunoglobulin. The provider should understand that the purpose of this injection is to prevent which of the following newborn complications?

• A. Hydrops fetalis
• B. Hypobilirubinemia
• C. Biliary atresia
• D. Transient clotting difficulties

Correct answer: B

Rationale: Rho (D) immunoglobulin is given to Rh-negative individuals to prevent hemolytic disease of the newborn (HDN) caused by Rh incompatibility between the mother and the fetus. If an Rh-negative mother carries an Rh-positive fetus, there is a risk of sensitization during pregnancy or childbirth. Sensitization can lead to the production of antibodies that may attack Rh-positive red blood cells in future pregnancies, potentially causing severe hemolytic disease in the newborn, including complications like hydrops fetalis. Hydrops fetalis is a condition characterized by severe edema and fetal organ enlargement due to severe anemia and heart failure in the fetus.
