Nursing Elites

1. When the nurse is determining the appropriate size of an oropharyngeal airway to insert, what part of a client's body should she measure?

• A. corner of the mouth to the tragus of the ear
• B. corner of the eye to the top of the ear
• C. tip of the chin to the sternum
• D. tip of the nose to the earlobe

Correct answer: B

Rationale: Correct! When sizing an oropharyngeal airway, the nurse should measure from the corner of the client's mouth to the tragus of the ear. This measurement ensures that the airway is the appropriate length to reach the pharynx without being too long or too short. Choices B, C, and D are incorrect as they do not provide the correct anatomical landmarks for determining the size of an oropharyngeal airway. Measuring from the corner of the mouth to the tragus of the ear is a standard method to ensure proper airway size and prevent complications during airway management.

2. The nurse provides a postoperative client with an analgesic medication and darkens the room before the client goes to sleep for the night. The nurse's actions:

• A. help decrease stimuli from the cerebral cortex.
• B. stimulate hormonal changes in the brain.
• C. help the client's circadian rhythm.
• D. alert the hypothalamus in the brain.

Correct answer: A

Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

3. Which hormone in the urine is specifically indicative of pregnancy?

• A. estrogen
• B. progesterone
• C. testosterone
• D. human chorionic gonadotropin

Correct answer: D

Rationale: Human chorionic gonadotropin is the hormone specifically indicative of pregnancy as it is produced by the placenta after implantation. It can be detected in urine and blood samples to confirm pregnancy. Estrogen and progesterone play crucial roles in the menstrual cycle and pregnancy but are not specific indicators of pregnancy on their own. Testosterone is a hormone primarily associated with male reproductive functions and is not directly related to pregnancy, making it an incorrect choice in this context.

4. Which of the following adverse effects should the client on Floxin be alerted to?

• A. stunting of height in teens and young adults
• B. propensity for anovulatory uterine bleeding
• C. intractable diarrhea
• D. tendon rupture

Correct answer: D

Rationale: The correct answer is tendon rupture. Floxin is a quinolone antibiotic commonly used in respiratory infections and pelvic/reproductive infections. One of the rare adverse effects associated with quinolones is tendon sheath rupture, often affecting the Achilles tendon. Therefore, patients taking Floxin should be alerted to the possibility of tendon rupture. Choices A, B, and C are incorrect as they are not typically associated with Floxin use and are not common adverse effects of quinolone antibiotics. Stunting of height is not a recognized adverse effect of Floxin. Anovulatory uterine bleeding is not a known side effect of quinolones. Intractable diarrhea is not a common adverse effect of Floxin.

5. Which is the proper hand position for performing chest vibration?

• A. cup the hands
• B. use the side of the hands
• C. flatten the hands
• D. spread the fingers of both hands

Correct answer: C

Rationale: The correct hand position for performing chest vibration is to flatten the hands. By flattening the hands over the area of the body where chest percussion is applied, vibrations can be conducted effectively to the chest to help loosen secretions. Cupping the hands may dampen vibrations, using the side of the hands reduces the surface area in contact with the chest, and spreading the fingers can lead to uneven pressure distribution. Therefore, flattening the hands provides the necessary contact and surface area to perform chest vibration efficiently.
