What drives respiration in a patient with advanced chronic respiratory failure?
- A. Hypoxemia
- B. Hypocapnia
- C. Hypercapnia
- D. None of the above
Correct Answer: A
Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

The parents of a child with a hernia are instructed by the nurse on measures to reduce the hernia. Which statement indicates the parents understand the care for their child?
- A. We will encourage our child to cough every few hours on a daily basis.
- B. We will make sure that our child participates in physical activity every day.
- C. We will provide comfort measures to reduce any crying periods by our child.
- D. We will be sure to give our child a Fleet enema every day to prevent constipation.
Correct Answer: C
Rationale: The correct answer is providing comfort measures to reduce any crying periods by the child. This can include offering a warm bath, avoiding upright positioning, and using other comfort measures to reduce crying, which can help reduce a hernia. Encouraging coughing or physical activity can increase strain on the hernia. Giving a Fleet enema daily for constipation is not recommended as it can also increase strain on the hernia.
A 25-year-old male client has been newly diagnosed with hypothyroidism and will take levothyroxine (Synthroid) 50 mcg/day by mouth. As part of the teaching plan, the nurse emphasizes that this medication:
- A. Should be taken in the morning
- B. May increase the client's energy level
- C. Does not need to be stored in a dark container
- D. May increase the client's heart rate
Correct Answer: A
Rationale: The correct answer is that levothyroxine (Synthroid) should be taken in the morning. Taking it in the morning can help prevent interference with the client's sleeping pattern, as one of the side effects of levothyroxine is insomnia. Choice B is incorrect because levothyroxine is actually used to treat hypothyroidism and can help increase energy levels. Choice C is incorrect as there is no specific requirement for levothyroxine to be stored in a dark container. Choice D is incorrect because levothyroxine is more likely to increase heart rate rather than decrease it.
While planning care for a 2-year-old hospitalized child, which situation would the nurse expect to most likely affect the behavior?
- A. Strange bed and surroundings
- B. Separation from parents
- C. Presence of other toddlers
- D. Unfamiliar toys and games
Correct Answer: B
Rationale: The correct answer is 'Separation from parents.' Separation anxiety is most evident from 6 months to 30 months of age and is the greatest stress imposed on a toddler by hospitalization. If separation is avoided, young children have a tremendous capacity to withstand other stress. The other choices, such as 'Strange bed and surroundings,' 'Presence of other toddlers,' and 'Unfamiliar toys and games,' may also have an impact on the child, but separation from parents is typically the most significant factor affecting behavior in a hospitalized 2-year-old.
The nurse has provided dietary instructions to the mother of a child with celiac disease. The nurse determines that further instruction is needed if the mother states that she will include which food item in the child's nutritional plan?
- A. Corn
- B. Chicken
- C. Oatmeal
- D. Vitamin supplements
Correct Answer: C
Rationale: In celiac disease, individuals need to avoid gluten-containing foods like wheat, rye, barley, and oats. Oatmeal contains gluten unless it is specifically labeled as gluten-free. Corn and rice are safe alternatives for individuals with celiac disease as they do not contain gluten. Chicken is a naturally gluten-free protein source. While vitamin supplements may be necessary to address deficiencies due to malabsorption, oatmeal poses a risk of gluten exposure, making it an incorrect choice for a child with celiac disease.
While suctioning the endotracheal tube of an adult client, what level of pressure should the nurse apply?
- A. 70-80 mmHg
- B. 100-120 mmHg
- C. 150-170 mmHg
- D. 200 mmHg
Correct Answer: B
Rationale: When suctioning the endotracheal tube of an adult client, the nurse should set the suction apparatus at a level no higher than 150 mmHg, with a preferable level between 100 and 120 mmHg. Suction pressure that is too high can contribute to the client's hypoxia. Alternatively, too low suction pressure may not clear adequate amounts of secretions. Choice A (70-80 mmHg) is too low and may not effectively clear secretions. Choices C (150-170 mmHg) and D (200 mmHg) are too high and can potentially harm the client by causing hypoxia or damaging the airway.
