Nursing Elites

1. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

2. Prior to a thoracentesis, which of the following actions should the nurse take?

• A. Position the client in an upright position, leaning over the bedside table.
• B. Explain the procedure.
• C. Obtain ABGs.
• D. Administer benzocaine spray.

Correct answer: A

Rationale: Positioning the client in an upright position, leaning over the bedside table helps to facilitate access to the thoracic cavity during the thoracentesis procedure. This position allows for easier identification and access to the insertion site. Explaining the procedure to the client is important, but positioning is the priority. Obtaining ABGs is not directly related to the thoracentesis procedure. Administering benzocaine spray is not a standard practice before a thoracentesis.

3. A client with heart failure has a new prescription for furosemide. Which of the following statements should the nurse make?

• A. Taking furosemide can cause your potassium levels to be high
• B. Eat foods that are high in sodium
• C. Rise slowly when getting out of bed
• D. Taking furosemide can cause you to be overhydrated

Correct answer: C

Rationale: Educating the client on the importance of rising slowly when getting out of bed is crucial due to the risk of orthostatic hypotension associated with furosemide use. This precaution helps prevent dizziness and falls. Options A and D are incorrect as furosemide commonly causes hypokalemia and dehydration, respectively, rather than high potassium levels or overhydration. Option B is inaccurate as clients on furosemide need to reduce sodium intake to manage fluid retention.

4. A client who is at 38 weeks gestation, is in active labor, and has ruptured membranes is being cared for by a nurse. What action should the nurse take?

• A. Insert an indwelling urinary catheter
• B. Apply fetal heart rate monitor
• C. Initiate fundal massage
• D. Initiate an oxytocin IV infusion

Correct answer: B

Rationale: When caring for a client in active labor with ruptured membranes, the priority action for the nurse is to apply a fetal heart rate monitor. This helps monitor the well-being of the fetus during labor and delivery, enabling timely interventions if any fetal distress is detected. Inserting an indwelling urinary catheter may be required in some cases, but it is not the priority in the given scenario. Fundal massage is typically done after delivery to help the uterus contract and prevent postpartum hemorrhage. Initiating an oxytocin IV infusion may be indicated to augment labor, but it is not the initial action needed in this situation.

5. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).
