Nursing Elites

1. When preparing to examine a client’s skin using a Wood light, what should the nurse do to facilitate this procedure?

• A. Darken the examining room
• B. Administer a local anesthetic
• C. Obtain a signed informed consent
• D. Shave the skin and scrub it with povidone-iodine (Betadine)

Correct answer: A

Rationale: When using a Wood light to examine the skin, the nurse should darken the examining room. This is necessary because the Wood light emits long-wavelength UV light, which is better visualized in a darkened environment. Administering a local anesthetic (Choice B) is not needed for this procedure. Obtaining a signed informed consent (Choice C) is not directly related to using a Wood light for skin examination. Shaving the skin and scrubbing it with povidone-iodine (Betadine) (Choice D) is not required and may not be appropriate for this type of skin examination.

2. A client who has heart failure is admitted with a serum potassium level of 2.9 mEq/L. Which action is most important for the nurse to implement?

• A. Administer 20 mEq of potassium chloride.
• B. Initiate continuous cardiac monitoring.
• C. Arrange a consultation with the dietitian.
• D. Educate about the side effects of diuretics.

Correct answer: B

Rationale: Hypokalemia, defined as a serum potassium level below the normal range of 3.5 to 5 mEq/L, can lead to changes in myocardial irritability and ECG waveform, potentially causing life-threatening dysrhythmias. Therefore, the priority action for the nurse is to initiate continuous cardiac monitoring to promptly detect any abnormal heart rhythms or ventricular ectopy. This monitoring is crucial for assessing the impact of potassium replacement therapy on the cardiac rhythm and ensuring the safety of the client. While administering potassium chloride is important for correcting the hypokalemia, it should occur after cardiac monitoring is in place. Consulting with a dietitian and educating about diuretic side effects are relevant aspects of care but are not the immediate priority in this situation where cardiac monitoring takes precedence for timely intervention.

3. A client is scheduled for an arteriogram. The nurse should explain to the client that the arteriogram will confirm the diagnosis of occlusive arterial disease by:

• A. Showing the location of the obstruction and the collateral circulation.
• B. Scanning the affected extremity and identifying the areas of volume changes.
• C. Using ultrasound to estimate the velocity changes in the blood vessels.
• D. Determining how long the client can walk.

Correct answer: A

Rationale: The correct answer is A: Showing the location of the obstruction and the collateral circulation. An arteriogram is a diagnostic procedure that involves injecting a contrast agent to visualize the blood vessels and identify the location of any obstructions. This helps confirm the diagnosis of occlusive arterial disease by showing where the blockage is located and how collateral circulation is compensating for the reduced blood flow. Choices B, C, and D are incorrect because scanning the extremity, estimating velocity changes with ultrasound, or determining walking distance are not the primary purposes of an arteriogram in diagnosing occlusive arterial disease.

4. Which of the following is a common cause of chronic obstructive pulmonary disease (COPD)?

• A. Smoking
• B. Asthma
• C. Allergies
• D. Chronic bronchitis

Correct answer: A

Rationale: Smoking is the correct answer as it is a well-established common cause of chronic obstructive pulmonary disease (COPD). Smoking leads to long-term damage to the lungs, contributing to the development of COPD. Choice B, asthma, is not a cause but a separate respiratory condition characterized by airway inflammation and hyperresponsiveness. Allergies, choice C, are not a direct cause of COPD but can exacerbate symptoms in individuals with existing COPD. Chronic bronchitis, choice D, is a type of COPD, not a cause of COPD itself, making it an incorrect choice in this context.

5. A patient presents with severe chest pain radiating to the left arm. Which of the following diagnostic tests is the priority?

• A. Complete blood count (CBC)
• B. Electrocardiogram (ECG)
• C. Chest X-ray
• D. Serum electrolytes

Correct answer: B

Rationale: In a patient presenting with severe chest pain radiating to the left arm, the priority diagnostic test is an Electrocardiogram (ECG) to assess for myocardial infarction. An ECG can quickly identify changes indicative of ischemia or infarction, guiding prompt management. A Complete Blood Count (CBC) may provide some information but is not the primary test for evaluating chest pain related to myocardial infarction. A Chest X-ray can be useful in assessing lung pathologies or certain cardiac conditions; however, it does not provide immediate information on myocardial infarction, making it a secondary option in this scenario. Serum electrolytes may become important in later stages but do not offer immediate insights into myocardial infarction. Therefore, they are a lower priority compared to obtaining an ECG for timely diagnosis and intervention.
