ATI 110 Fundamentals Exam 1 Questions
Extract:
Question 1 of 5
A nurse is teaching a class about sleep disorders. The nurse should include that which of the following conditions can cause obstructive sleep apnea (OSA)?
Correct Answer: D
Rationale: The correct answer is D: Enlarged tonsils. Enlarged tonsils can physically obstruct the airway during sleep, leading to obstructive sleep apnea (OS
A). This obstruction causes pauses in breathing during sleep, resulting in disrupted sleep patterns and decreased oxygen levels in the blood. Heart failure (
A) is incorrect because it is not a direct cause of OSA. Brainstem injury (
B) may disrupt the sleep-wake cycle but is not a common cause of OSA. Recent weight loss (
C) can actually improve OSA symptoms by reducing the amount of tissue in the airway.
Therefore, the most likely condition to cause OSA among the choices given is enlarged tonsils.
Question 2 of 5
A nurse is preparing to lift a heavy object. Which of the following actions by the nurse indicates understanding of body mechanics?
Correct Answer: C
Rationale: The correct answer is C: They stand close to the object being moved. This action indicates understanding of body mechanics as it reduces the strain on the back by keeping the load close to the body's center of gravity. Standing close to the object allows for better leverage and control during the lift, minimizing the risk of injury.
Rationale for why other choices are incorrect:
A: Bending at the hip when lifting can put excessive strain on the lower back.
B: Keeping feet together may lead to instability and lack of balance during lifting.
D: Twisting the spine when lifting can result in spinal injuries and muscle strain.
Question 3 of 5
A nurse is taking care of a patient that has a new prescription for labetalol (beta blocker). What adverse effect should the nurse include in the medication education?
Correct Answer: C
Rationale: The correct answer is C: Bradycardia. Labetalol is a beta blocker that slows down the heart rate by blocking beta-adrenergic receptors. This can lead to bradycardia, which is a slow heart rate. The nurse should educate the patient about this potential adverse effect to prevent any complications.
Hypokalemia (choice
A) is not a common adverse effect of labetalol. Bleeding (choice
B) is not directly associated with beta blockers like labetalol. Seizures (choice
D) are not a typical adverse effect of labetalol.
Therefore, the correct answer is C as it directly correlates with the mechanism of action of labetalol.
Question 4 of 5
A nurse is assessing a client who has a wound that is healing by primary intention. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: The correct answer is C: Skin edges of the wound are sutured closed. In primary intention healing, the wound edges are approximated and closed with sutures, promoting faster healing and minimal scarring. Granulation tissue (
A) is seen in secondary intention healing. Healing is not prolonged (
B) in primary intention healing. Wound contamination (
D) is not a characteristic of primary intention healing.
Question 5 of 5
A client is to receive enoxaparin 30 mg subcutaneously. Available is enoxaparin 40 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.8
Rationale: The correct answer is 0.8 mL.
To determine this, divide the desired dose (30 mg) by the concentration (40 mg/mL) to get 0.75. Since we need to round to the nearest tenth, 0.75 rounds up to 0.8 mL. The other choices are incorrect because: A: 0.7 mL, B: 0.9 mL, C: 0.6 mL, D: 1.0 mL, E: 0.5 mL, F: 1.2 mL, G: 0.3 mL. These choices do not accurately reflect the calculated dose based on the given information.
