Nursing Elites

1. 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.

2. A sexually active adolescent asks the school nurse about the use of latex condoms and the reduction of the risk of sexually transmitted infections (STIs). The nurse provides which information to the adolescent?

• A. Using a latex condom is a good method for reducing the risk of sexually transmitted infections (STIs).
• B. The only way to reduce the risk of transmission of STIs is abstinence.
• C. A spermicide needs to be used along with a condom to prevent transmission of STIs.
• D. Using a latex condom can reduce the risk of transmission of STIs.

Correct answer: D

Rationale: The correct answer is that using a condom during intercourse can reduce the risk of STI transmission. Abstinence is a way to prevent STIs, but not the only way. Using a spermicide along with a condom can help prevent pregnancy, not STIs. While condoms may fail to prevent pregnancy, they are effective in reducing the risk of STI transmission. Therefore, using a latex condom for pregnancy prevention is not directly related to preventing the transmission of STIs.

3. A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?

• A. The fingers curl tightly, and the toes curl forward.
• B. The toes flare, and the big toe is dorsiflexed.
• C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
• D. The infant turns to the side that is touched.

Correct answer: B

Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.

4. A woman in labor whose cervix is not completely dilated is pushing strenuously during contractions. Which method of breathing should the nurse encourage the woman to perform to help her overcome the urge to push?

• A. Holding her breath and using the Valsalva maneuver
• B. Blowing repeatedly in short puffs
• C. Cleansing breaths
• D. Deep inspiration and expiration at the beginning and end, respectively, of each contraction

Correct answer: B

Rationale: If a woman pushes strenuously before the cervix is completely dilated, she risks injury to the cervix and the fetal head. Blowing prevents closure of the glottis and breath-holding, helping overcome the urge to push strenuously. The woman would be encouraged to blow repeatedly, using short puffs, when the urge to push is strong. This breathing technique allows for controlled exhalation and helps prevent unnecessary pushing. Cleansing breaths (deep inspiration and expiration at the beginning and end of each contraction) are encouraged during the first stage of labor to provide oxygenation and reduce myometrial hypoxia and to promote relaxation. Holding her breath and using the Valsalva maneuver (choice A) is not recommended as it can increase intra-abdominal pressure and decrease venous return, potentially compromising fetal oxygenation. Deep inspiration and expiration at the beginning and end of each contraction (choice D) are more suitable for relaxation and oxygenation purposes rather than managing the urge to push.

5. A healthcare provider is preparing to perform a Rinne test on a client who complains of hearing loss. In which area does the healthcare provider first place an activated tuning fork?

• A. On the client's teeth
• B. On the client's forehead
• C. On the client's mastoid bone
• D. On the midline of the client's skull

Correct answer: C

Rationale: In the Rinne test, the base of an activated tuning fork is held first against the mastoid bone, behind the ear, and then in front of the ear canal (0.5 to 2 inches). When the client no longer perceives the sound behind the ear, the fork is moved in front of the ear canal until the client indicates that the sound can no longer be heard. The client reports whether the sound from the tuning fork is louder behind the ear (on the mastoid bone) or in front of the ear canal. Placing the tuning fork on the teeth (Choice A), forehead (Choice B), or the midline of the skull (Choice D) is not part of the Rinne test procedure. Therefore, the correct answer is to first place the activated tuning fork on the client's mastoid bone.
