Nursing Elites

1. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

2. A client is scheduled for an Intravenous Pyelogram (IVP). In order to prepare the client for this test, the nurse would:

• A. Instruct the client to maintain a regular diet the day prior to the examination
• B. Restrict the client's fluid intake 4 hours prior to the examination
• C. Administer a laxative to the client the evening before the examination
• D. Inform the client that only 1 x-ray of his abdomen is necessary

Correct answer: C

Rationale: Administering a laxative to the client the evening before the examination is the correct action. Bowel prep is crucial for an Intravenous Pyelogram (IVP) as it helps in achieving better visualization of the bladder and ureters. Instructing the client to maintain a regular diet the day prior to the examination (Choice A) is not the appropriate preparation for an IVP. Restricting the client's fluid intake 4 hours prior to the examination (Choice B) is not necessary for this test. Informing the client that only 1 x-ray of his abdomen is necessary (Choice D) is not relevant to the preparation process for an IVP.

3. A client using an intraaural hearing aid experiences whistling after placement. What is the nurse's next action?

• A. Try to reposition the hearing aid
• B. Change the batteries
• C. Remove the device and have it cleaned
• D. Notify the physician that the hearing aid is not working

Correct answer: A

Rationale: An intraaural hearing aid, also known as an in-the-ear hearing aid, is placed in the ear canal. Whistling after placement indicates improper positioning of the device. The correct action for the nurse is to try repositioning the hearing aid to eliminate the whistling. Changing the batteries is not necessary for addressing whistling. Removing the device to clean it is not the immediate action needed for whistling. Notifying the physician is premature without attempting to reposition the hearing aid first.

4. A nurse is caring for a patient after a coronary angiogram. Which of these actions taken by the nursing assistant would most require the nurse's immediate intervention?

• A. The nursing assistant fills the patient's pitcher with ice-cold drinking water
• B. The nursing assistant elevates the head of the bed to 60 degrees for a meal
• C. The nursing assistant refills the ice pack placed on the insertion site
• D. The nursing assistant places an extra pillow under the patient's head upon request

Correct answer: B

Rationale: After a coronary angiogram, patients need to maintain bed rest and keep the head of the bed at no more than 30 degrees for 3-6 hours, depending on the insertion site. Elevating the head of the bed to 60 degrees for a meal could increase the risk of bleeding or complications at the insertion site. Refilling the ice pack placed on the insertion site is appropriate for managing potential swelling or discomfort. Filling the patient's pitcher with ice-cold drinking water is a standard care task. Placing an extra pillow under the patient's head upon request is a comfort measure and does not pose a risk to the patient's recovery.

5. A man is prescribed lithium to treat bipolar disorder. The nurse is most concerned about lithium toxicity when he notices which of these assessment findings?

• A. The patient states he had a manic episode a week ago
• B. The patient states he has been having diarrhea every day
• C. The patient presents as severely depressed
• D. The patient has a rash and pruritus on his arms and legs

Correct answer: B

Rationale: The correct answer is when the patient states he has been having diarrhea every day. Persistent diarrhea can lead to dehydration, which can increase the risk of lithium toxicity. The other options, such as a manic episode, severe depression, or rash and pruritus, are not directly associated with an increased risk of lithium toxicity.
