Which of the ff. would the nurse explain to a patient is the main purpose of a hearing aid?
- A. Amplify background noise
- B. Amplify musical sounds
- C. Occlude the ear
- D. Improve ability to hear
Correct Answer: D
Rationale: The main purpose of a hearing aid is to improve the patient's ability to hear. Hearing aids are devices designed to amplify sound for individuals with hearing loss or difficulty hearing. They do not amplify background noise or musical sounds specifically; instead, they are meant to enhance the overall perception of sounds to help individuals better understand speech and communicate effectively. Moreover, hearing aids do not occlude the ear, but rather are used to transmit sound into the ear canal to make sounds louder and clearer for the wearer.
Patient S is a sexually active adolescent; which of the following instructions would be included in the preventive teaching plan about urinary tract infections?
- A. Drinking acidic juices
- B. Avoiding urinating before intercourse
- C. Wearing nylon underwear
- D. Wiping back to front
Correct Answer: A
Rationale: Drinking acidic juices, such as cranberry juice, can help make the urine more acidic, which can potentially prevent bacteria from sticking to the urinary tract walls and reduce the risk of urinary tract infections. It is important to note that while acidic juices can be beneficial in some cases, they should not be relied upon as the sole preventive measure for UTIs. Other important preventive measures include staying hydrated, practicing good hygiene, and urinating before and after intercourse.
A school nurse is conducting vision and hearing testing on fifth-grade children. Which level of prevention is the nurse demonstrating?
- A. Primary
- B. Secondary
- C. Tertiary
- D. Health promotion
Correct Answer: B
Rationale: The school nurse conducting vision and hearing testing on fifth-grade children is demonstrating the secondary level of prevention. Secondary prevention involves identifying and treating health conditions early to prevent their progression. In this scenario, the nurse's aim is to detect any existing vision or hearing problems in the children at an early stage so that appropriate interventions can be initiated to prevent further impairment or complications. This aligns with the goals of secondary prevention, which focuses on early detection, prompt intervention, and minimizing the impact of a health condition.
An insulin-dependent diabetic delivered a 10-pound male. When the baby is brought to the nursery, the priority of care is to
- A. clean the umbilical cord with Betadine to prevent infection
- B. give the baby a bath
- C. call the laboratory to collect a PKU screening test
- D. check the baby's serum glucose level and administer glucose if < 40 mg/dL
Correct Answer: D
Rationale: The priority of care when a baby born to an insulin-dependent diabetic mother is brought to the nursery is to check the baby's serum glucose level and administer glucose if it is less than 40 mg/dL. Babies born to diabetic mothers, especially those with poorly controlled blood sugar levels, are at risk for hypoglycemia (low blood sugar) due to the sudden drop in glucose supply after delivery. Hypoglycemia can be dangerous for newborns and can lead to serious complications if left untreated. Therefore, monitoring the baby's serum glucose levels and providing appropriate intervention, such as administering glucose if necessary, is critical to ensure the baby's well-being.
An 8-day-old is admitted with vomiting and dehydration. His HR is 170, RR is 44, BP is 85/52, and T is 99°F. The parents ask if these vital signs are normal. Which is the best response?
- A. The BP is elevated.
- B. The temperature is elevated.
- C. The heart rate is elevated; normal for a neonate is 90-160 bpm.
- D. The respiratory rate is elevated.
Correct Answer: C
Rationale: A neonatal heart rate of 170 is above the normal range (90-160 bpm), which is concerning for dehydration.
