NCLEX RN Practice Questions Quizlet
1. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?
- A. It is the correct dose
- B. The dose is too low
- C. The dose is too high
- D. The dose should be increased or decreased, depending on the symptoms
Correct answer: B
Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.
2. While caring for the client during the first hour after delivery, the nurse determines that the uterus is boggy and there is vaginal bleeding. What should be the nurse's first action?
- A. Check vital signs
- B. Massage the fundus
- C. Offer a bedpan
- D. Check for perineal lacerations
Correct answer: B
Rationale: Massage the fundus. The nurse's first action should be to massage the fundus until it is firm as uterine atony is the primary cause of bleeding in the first hour after delivery. Checking vital signs, offering a bedpan, or checking for perineal lacerations are important assessments but addressing the boggy uterus and vaginal bleeding due to uterine atony takes precedence in this situation.
3. When caring for an asthmatic patient with an early-phase reaction, which of the following is indicative of an early-phase reaction?
- A. Rapid bronchospasms
- B. Inflammatory epithelial lesions
- C. Increased secretions
- D. Increased mucosal edema
Correct answer: A
Rationale: Rapid bronchospasms are a symptom of an early-phase reaction in an asthmatic patient. During the early phase, bronchospasms occur due to immediate hypersensitivity reactions. Inflammatory epithelial lesions, increased secretions, and increased mucosal edema are typically seen in late-phase reactions as part of the inflammatory response that occurs later. Therefore, rapid bronchospasms are most indicative of an early-phase reaction.
4. A client has just been diagnosed with active tuberculosis. Which of the following nursing interventions should the nurse perform to prevent transmission to others?
- A. Begin drug therapy within 72 hours of diagnosis
- B. Place the client in a positive-pressure room
- C. Initiate standard precautions
- D. Place the client in a negative-pressure room
Correct answer: D
Rationale: A client diagnosed with active tuberculosis should be placed in isolation in a negative-pressure room to prevent transmission of infection to others. Placing the client in a negative-pressure room ensures that air is exhausted to the outside and received from surrounding areas, preventing tuberculin particles from traveling through the ventilation system and infecting others. Initiating standard precautions, as mentioned in choice C, is essential for infection control but is not specific to preventing transmission in the case of tuberculosis. Beginning drug therapy within 72 hours of diagnosis, as in choice A, is crucial for the treatment of tuberculosis but does not directly address preventing transmission. Placing the client in a positive-pressure room, as in choice B, is incorrect as positive-pressure rooms are used for clients with compromised immune systems to prevent outside pathogens from entering the room, which is not suitable for a client with active tuberculosis.
5. 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.
