1. A client is having difficulty breathing while laying in bed with a nasal cannula delivering oxygen. Which of the following interventions should the nurse take first?
- A. Suction the client's airway
- B. Administer a bronchodilator
- C. Increase the humidity in the client's room
- D. Assist the client to an upright position
Correct answer: D
Rationale: The correct answer is to assist the client to an upright position. When a client is having difficulty breathing, promoting optimal oxygenation is essential. Elevating the head of the bed improves ventilation and lung expansion by reducing pressure on the diaphragm. This position allows the lungs to expand fully, enhancing oxygen exchange. Suctioning the airway may be necessary if there are secretions causing obstruction, but it is not the first intervention in this scenario. Administering a bronchodilator is appropriate for bronchoconstriction but does not address the immediate need for better ventilation. Increasing humidity can be beneficial in certain respiratory conditions, but it is not the initial priority when a client is struggling to breathe.
2. What is the expected date of delivery for a woman whose last menstrual period was on April 20th?
- A. January 20th
- B. January 27th
- C. January 29th
- D. January 31st
Correct answer: B
Rationale: The expected date of delivery is calculated by adding 9 months and 7 days to the last menstrual period. For April 20th, the expected date is January 27th. Therefore, the correct answer is B. Choice A, January 20th, is incorrect as it does not account for the additional 7 days. Choice C, January 29th, and Choice D, January 31st, are also incorrect as they do not consider the standard calculation method for estimating the due date.
3. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?
- A. 100 mL/hour.
- B. 125 mL/hour.
- C. 133 mL/hour.
- D. 150 mL/hour.
Correct answer: C
Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.
4. A client has active genital herpes simplex virus type 2. Which of the following medications should the nurse plan to administer?
- A. Metronidazole
- B. Penicillin
- C. Acyclovir
- D. Gentamicin
Correct answer: C
Rationale: Acyclovir is the antiviral medication specifically used to treat herpes simplex virus infections, including genital herpes caused by herpes simplex virus type 2. Metronidazole (Choice A) is an antibiotic used for different types of infections, but not for viral infections like herpes. Penicillin (Choice B) is an antibiotic effective against bacterial infections, not viruses like herpes. Gentamicin (Choice D) is an antibiotic mainly used to treat bacterial infections, not viral infections like herpes.
5. A client is being taught how to self-administer daily low-dose heparin injections. Which of the following factors is most likely to increase the client’s motivation to learn?
- A. The client’s belief that his needs will be met through education
- B. The nurse’s empathy regarding the client's self-injection
- C. The client seeking family approval by agreeing to a teaching plan
- D. The nurse explaining the need for education to the client
Correct answer: A
Rationale: The client's belief that his needs will be met through education is the most likely factor to increase motivation to learn. When individuals perceive that their educational efforts will directly benefit them, they are more motivated to engage in the learning process. Empathy from the nurse, seeking family approval, or the nurse explaining the need for education may not be as directly tied to the client's personal benefit and may not necessarily increase motivation to learn.
