Nursing Elites

1. Which of the following interventions is necessary before insertion of an arterial line into the radial artery?

• A. Ensure that the client does not need surgery
• B. Assess the client's grip strength
• C. Perform an Allen test
• D. Check a serum potassium level

Correct answer: C

Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line. Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.

2. A client has started sweating profusely due to intense heat. His overall luid volume is low and he has developed electrolyte imbalance. This client is most likely suffering from:

• A. Malignant hyperthermia
• B. Heat exhaustion
• C. Heat stroke
• D. Heat cramps

Correct answer: B

Rationale: Heat exhaustion occurs when a person has enough diaphoresis that he becomes dehydrated. Intense sweating can cause both luid and electrolyte imbalances. Untreated heat exhaustion can lead to heat stroke, which results in organ damage, loss of consciousness, or death.

3. Which behavior observed by the nurse indicates a suspicion that a depressed adolescent client may be suicidal?

• A. The adolescent gives away a DVD player and a cherished autographed picture of a performer.
• B. The adolescent runs out of group therapy, swearing at the group leader, and then goes to her room.
• C. The adolescent becomes angry while speaking on the phone and slams down the receiver.
• D. The adolescent gets angry with her roommate when the roommate borrows her clothes without asking.

Correct answer: A

Rationale: The correct answer is when the adolescent gives away a DVD player and a cherished autographed picture of a performer. This behavior is concerning because a depressed suicidal client often gives away things of value as a way of saying goodbye and wanting to be remembered. Choices B, C, and D all involve anger and acting-out behaviors, which are common in adolescents but do not specifically indicate suicidal ideation. Running out of group therapy, swearing, and going to her room, becoming angry and slamming the phone receiver, or getting upset when her roommate borrows her clothes are not clear indications of suicidal thoughts.

4. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

• A. External light sources may cause falsely high oximetry values
• B. A bright light in the client's face may cause a low pulse oximetry
• C. External light sources may cause falsely low oximetry values
• D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.

5. Plantar flexion can be prevented with ________________.

• A. foot soaks
• B. foot boards
• C. toenail care
• D. proper shoes

Correct answer: B

Rationale: Plantar flexion, or foot drop, can be prevented with foot boards, special splints, and range of motion exercises. Foot boards help maintain the foot in a neutral position, preventing contractures and deformities. Foot soaks (choice A) may help with foot hygiene but do not directly prevent plantar flexion. Toenail care (choice C) is important for overall foot health but does not prevent plantar flexion. Proper shoes (choice D) are essential for foot support and comfort but do not specifically prevent plantar flexion.
