Nursing Elites

1. A nurse preparing to examine a client’s eyes plans to perform a confrontation test. The nurse tells the client that this test measures which aspect of vision?

• A. Near vision
• B. Color vision
• C. Distant vision
• D. Peripheral vision

Correct answer: D

Rationale: The correct answer is D: Peripheral vision. The confrontation test is a gross measure of peripheral vision. It compares the client’s peripheral vision with the nurse’s, assuming that the nurse’s vision is normal. During the test, the nurse positions themselves at eye level with the client, about 2 feet away, and directs the client to cover one eye with an opaque card. The nurse covers the eye opposite the client’s covered one and slowly moves a target (like a pencil) from the periphery in several directions. The client is asked to indicate when they see the target, which should coincide with when the nurse sees it. Near vision is tested using a handheld vision screener with various sizes of print, color vision with the Ishihara test, and distant vision with a Snellen chart. Therefore, choices A, B, and C are incorrect as they do not measure peripheral vision, which is the focus of the confrontation test.

2. What classification of drug is Diltiazem?

• A. Calcium-Channel Blocker
• B. NSAID
• C. ACE Inhibitor
• D. Beta-Blocker

Correct answer: A

Rationale: Diltiazem belongs to the class of calcium-channel blockers, not NSAIDs, ACE Inhibitors, or Beta-Blockers. Calcium-channel blockers like Diltiazem are used to treat conditions such as hypertension by relaxing blood vessels and increasing the supply of blood and oxygen to the heart. Therefore, the correct classification for Diltiazem is a Calcium-Channel Blocker. NSAIDs, ACE Inhibitors, and Beta-Blockers belong to different classes of drugs with distinct mechanisms of action and therapeutic uses, making them incorrect choices for Diltiazem.

3. Which of these is not a symptom of Serotonin Syndrome?

• A. edema
• B. fever
• C. confusion
• D. tremors

Correct answer: A

Rationale: Serotonin syndrome, caused by an excess of serotonin, typically presents with symptoms such as altered mental status (confusion), neuromuscular abnormalities (tremors), and autonomic dysfunction (fever). Edema, which refers to swelling caused by fluid retention in the body tissues, is not a common symptom associated with serotonin syndrome. Therefore, the correct answer is 'edema.' Choice A, 'edema,' is the correct answer as it is not typically seen in serotonin syndrome. Choice B, 'fever,' is a symptom of serotonin syndrome, as it can cause autonomic dysfunction. Choice C, 'confusion,' is a common symptom due to altered mental status in serotonin syndrome. Choice D, 'tremors,' is also a common symptom due to neuromuscular abnormalities in serotonin syndrome.

4. The LPN is taking care of a 176-pound client who has recently been diagnosed with diabetes. The primary healthcare provider has written an order for Lantus� (insulin glargine injection) 100 units/mL, using weight-based dosing of 0.2 units/kg per day. The LPN should prepare ____ units for administration.

• A. 12
• B. 35
• C. 16
• D. 9

Correct answer: B

Rationale: To calculate the correct dosage, first convert the client's weight from pounds to kilograms. As 1 kg = 2.2 pounds, 176 pounds � 2.2 = 80 kg. The client should receive 0.2 units for every kilogram, which equals 16 units. Therefore, the total amount to prepare is 16 units x 100 units/mL = 1600 units. Considering the medication concentration of 100 units/mL, 1600 units � 100 units/mL = 16 mL. However, since the question asks for the number of units, the final answer is 16 units x 2 injections = 32 units. Therefore, the LPN should prepare 32 units for administration.

5. During the examination of a client's throat, a nurse touches the posterior wall with a tongue blade and elicits the gag reflex. The nurse documents normal function of which cranial nerves?

• A. Cranial nerves V and VI
• B. Cranial nerves XII and VIII
• C. Cranial nerves XII and VIII
• D. Cranial nerves IX and X

Correct answer: D

Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.
