Nursing Elites

1. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

2. 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.

3. What is required for effective hand washing?

• A. Soap or detergent to promote emulsification
• B. Hot water to destroy bacteria
• C. A disinfectant to increase surface tension
• D. All of the above

Correct answer: A

Rationale: To effectively wash hands, soap or detergent is essential as they help emulsify fats and oils, allowing them to be rinsed away. Hot water alone cannot effectively destroy bacteria, and a disinfectant is not typically required for routine hand washing.

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. A healthcare professional is preparing to administer a dose of a new prescription of prednisone to a client who has COPD. The healthcare professional should not concentrate on which of the following adverse effects of this medication?

• A. Hypokalemia
• B. Tachycardia
• C. Fluid retention
• D. Black, tarry stools

Correct answer: B

Rationale: When administering prednisone, a corticosteroid medication, to a client with COPD, the healthcare professional should be aware of potential adverse effects. Tachycardia is not a common adverse effect of prednisone use. The correct adverse effects to monitor for include hypokalemia, fluid retention, and gastrointestinal issues like black, tarry stools due to potential gastrointestinal bleeding. Therefore, the healthcare professional should not concentrate on tachycardia but should focus on the other listed adverse effects when administering prednisone to a client with COPD.
