1. A group of newly licensed nurses is being taught about the Braden Scale by a nurse. Which of the following responses by a newly licensed nurse indicates an understanding of the teaching?
- A. “The client’s age is not a factor in the measurement.”
- B. “The scale measures six elements.”
- C. “A lower score indicates a higher risk of pressure ulcers.”
- D. “Each element is scored on a range from 1 to 4 points.”
Correct answer: B
Rationale: Choice B is the correct answer because the Braden Scale measures six elements: Sensory Perception, Moisture, Activity, Mobility, Nutrition, Friction, and Shear. The other choices are incorrect because: Choice A states that the client's age is not a factor in the measurement, which is accurate as age is not included in the Braden Scale. Choice C incorrectly states that a lower score indicates a higher risk of pressure ulcers, which is the opposite of how the Braden Scale works. Choice D inaccurately describes the scoring range of each element on the Braden Scale, which is not from 1 to 4 points but rather from 1 to 3.
2. What causes cystic fibrosis?
- A. Sex-linked abnormality.
- B. Abnormality in the 21st pair of chromosomes.
- C. Recessive gene.
- D. Single segment found only on the Y chromosome.
Correct answer: C
Rationale: Cystic fibrosis is a genetic disorder caused by inheriting two copies of a recessive gene, one from each parent. This means that both parents must carry at least one copy of the faulty gene for a child to inherit the condition. Choice A is incorrect because cystic fibrosis is not linked to the sex chromosomes. Choice B is incorrect as cystic fibrosis is not caused by an abnormality in the 21st pair of chromosomes but by a specific gene mutation. Choice D is also incorrect as cystic fibrosis is not related to the Y chromosome, which is specific to males.
3. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy at 2 liters per minute via a nasal cannula. Which assessment finding indicates a potential complication of oxygen therapy?
- A. Increased respiratory rate
- B. Decreased level of consciousness
- C. Improved oxygen saturation
- D. Complaints of dry mouth
Correct answer: B
Rationale: In clients with COPD, oxygen therapy can lead to a decrease in the respiratory drive caused by the removal of the hypoxic drive. This can result in carbon dioxide retention, leading to a decreased level of consciousness. Options A, C, and D are incorrect because an increased respiratory rate is typically a sign of hypoxia, improved oxygen saturation is a positive response to oxygen therapy, and complaints of dry mouth are not directly related to oxygen therapy complications in this scenario.
4. During a health screening, a client's blood pressure reads 160/100 mm Hg. What should the nurse recommend?
- A. Schedule a follow-up appointment
- B. Start making immediate dietary changes
- C. Begin an exercise program
- D. All of the above
Correct answer: A
Rationale: A follow-up with a healthcare provider is necessary to assess and manage the newly identified hypertension. While dietary changes and exercise are important for managing high blood pressure, immediate lifestyle modifications without further evaluation by a healthcare provider may not be safe or effective. Option A is the most appropriate initial step to ensure proper assessment and management of the client's blood pressure. Therefore, choices B and C are incorrect in this scenario. Option D is also incorrect because not all options should be implemented without proper medical guidance.
5. During a well-child check-up, what respiratory assessment finding should the nurse anticipate in a 3-year-old?
- A. A resting respiratory rate of 40 breaths per minute
- B. Bronchovesicular breath sounds in the peripheral lung fields
- C. Retractions in the intercostal spaces with each inspiration
- D. High-pitched whistling sounds over the bronchi
Correct answer: A
Rationale: A resting respiratory rate of 40 breaths per minute is within the expected range for a 3-year-old child. This is considered normal in this age group as their respiratory rate is generally higher compared to adults. Bronchovesicular breath sounds in the peripheral lung fields are not an expected finding in a 3-year-old. Retractions in the intercostal spaces with each inspiration indicate increased work of breathing and are abnormal. High-pitched whistling sounds over the bronchi are characteristic of wheezing, which is not typically expected in a healthy 3-year-old during a routine check-up.
