Nursing Elites

1. A nurse cares for a client with diabetes mellitus who is prescribed metformin (Glucophage) and is scheduled for an intravenous urography. Which action should the nurse take first?

• A. Contact the provider and recommend discontinuing the metformin.
• B. Keep the client NPO for at least 6 hours prior to the examination.
• C. Check the client’s capillary artery blood glucose and administer prescribed insulin.
• D. Administer intravenous fluids to dilute and increase the excretion of dye.

Correct answer: A

Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client’s health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client’s blood glucose, and administering intravenous fluids should be part of the client’s plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.

2. The client is receiving teletherapy radiation for a malignant tumor. Which instruction regarding skin care of the portal site should the nurse provide?

• A. Protect the skin of the radiation portal site from sunlight exposure
• B. Apply moisturizing lotions daily to the radiation portal site
• C. Avoid washing the skin inside the radiation portal site
• D. Remove the ink marks of the portal after each radiation treatment

Correct answer: A

Rationale: Protecting the skin from sunlight exposure is crucial to prevent radiation burns and additional skin damage at the treatment site. Sun exposure can exacerbate skin reactions caused by radiation therapy. Applying moisturizing lotions daily may introduce foreign substances or irritants to the treated area, leading to potential complications. Washing the skin inside the radiation portal site is important for maintaining cleanliness and preventing infections. Removing the ink marks after each treatment is unnecessary and may cause unnecessary skin irritation and trauma.

3. Prior to a percutaneous kidney biopsy, which actions should a nurse take? (Select all that apply.)

• A. Keep the client NPO for 4 to 6 hours.
• B. Obtain coagulation study results.
• C. Maintain strict bedrest in a supine position.
• D. A & B

Correct answer: D

Rationale: Prior to a percutaneous kidney biopsy, the nurse should ensure that the client is kept NPO for 4 to 6 hours to prevent aspiration during the procedure. Obtaining coagulation study results is crucial to assess the risk of bleeding during and after the biopsy. Strict bedrest in a supine position is not necessary before the procedure. It is important to note that blood pressure medications should be carefully managed, but it is not a pre-procedure action. Keeping the client on bedrest or assessing for blood in the urine are interventions that are more relevant post-procedure to monitor for complications.

4. A client who has just undergone surgery suddenly experiences chest pain, dyspnea, and tachypnea. The nurse suspects that the client has a pulmonary embolism and immediately sets about:

• A. Preparing the client for a perfusion scan
• B. Attaching the client to a cardiac monitor
• C. Administering oxygen via nasal cannula
• D. Ensuring that the intravenous (IV) line is patent

Correct answer: C

Rationale: When a client who has just undergone surgery experiences sudden chest pain, dyspnea, and tachypnea, indicating possible pulmonary embolism, the immediate priority for the nurse is to administer oxygen via nasal cannula. This intervention aims to improve oxygenation and alleviate respiratory distress, which is crucial in the setting of a potential pulmonary embolism. Preparing the client for a perfusion scan is not the immediate priority as stabilizing the client's respiratory status comes first. While attaching the client to a cardiac monitor is important for monitoring, administering oxygen takes precedence in this situation. Ensuring IV line patency is relevant for overall client care but is not the priority when a client is experiencing respiratory distress requiring immediate intervention.

5. In a patient with asthma, which of the following is the most important indicator of respiratory function?

• A. Oxygen saturation.
• B. Respiratory rate.
• C. Arterial blood gases.
• D. Peak expiratory flow rate.

Correct answer: D

Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.
