A newborn is diagnosed with retinopathy of prematurity. What should the nurse know about this diagnosis?
- A. Blindness cannot be prevented.
- B. No treatment is currently available.
- C. Cryotherapy and laser therapy are effective treatments.
- D. Long-term administration of oxygen will be necessary.
Correct Answer: C
Rationale: Retinopathy of prematurity (ROP) is a disorder of the developing retinal blood vessels in premature infants. Cryotherapy and laser therapy are both effective treatments for ROP. These treatments can help prevent vision loss and improve the chances of maintaining good vision. Prompt detection and intervention are key in managing ROP to prevent long-term visual impairment. Therefore, the nurse should be aware that cryotherapy and laser therapy are effective interventions for ROP, contrary to the options suggesting blindness cannot be prevented or no treatment is available. Long-term administration of oxygen can contribute to the development of ROP, so careful monitoring and management of oxygen levels are necessary in premature infants to prevent this condition.

When teaching a client about insulin administration, the nurse should include which instruction?
- A. "Administer insulin after the first meal of the day."
- B. "Inject insulin at a 45-degree angle into the deltoid muscle."
- C. "Shake the insulin vial vigorously before withdrawing the medication."
- D. "Draw up clear insulin first when mixing two types of insulin in one syringe."
Correct Answer: D
Rationale: When mixing two types of insulin in one syringe, it is essential to draw up the clear insulin first before drawing up the cloudy insulin. This sequence prevents the clear insulin from becoming contaminated with the cloudy insulin and ensures accurate dosing. Drawing up the clear insulin first helps to minimize the risk of inaccurate dosing and maintains the effectiveness of the insulin being administered.
A client asks the nurse what PSA is. The nurse should reply that is stands for:
- A. Prostate-specific antigen, which is used to screen for prostate cancer
- B. Protein serum antigen, which is used to determine protein levels
- C. Pneumococcal strep antigen, which is bacteria that causes pneumonia
- D. Papanicolua-specific antigen, which is used to screen for cervical cancer
Correct Answer: A
Rationale: PSA stands for Prostate-specific antigen, which is a protein produced by both cancerous and noncancerous cells in the prostate gland. It is primarily used as a screening test for prostate cancer. Elevated levels of PSA in the blood may indicate the presence of prostate cancer or other prostate conditions. Regular PSA testing is often recommended for men over a certain age to help detect prostate cancer early when it is more treatable.
An elderly patient, Mr. Cruz is being cared for by nurse Bennie because of pulmonary embolism. Nurse Bennie would anticipate an order for immediate administration of:
- A. warfarin
- B. heparin
- C. dexamethazone
- D. protamine sulfate
Correct Answer: B
Rationale: In the scenario of an elderly patient like Mr. Cruz with suspected pulmonary embolism, the nurse would anticipate an order for the immediate administration of heparin. Heparin is an anticoagulant medication that works quickly to prevent the further development of blood clots. It is often used as the initial treatment for pulmonary embolism to prevent existing blood clots from getting larger and reduce the risk of new clots forming. Heparin is preferred over warfarin initially because it has a more rapid onset of action. Warfarin, which is a commonly used anticoagulant for longer-term management, takes several days to reach its full effect and requires monitoring of the prothrombin time (INR). Therefore, in Mr. Cruz's acute situation, heparin would be the most appropriate choice for immediate intervention to address the pulmonary embolism.
The parent of a child with glomerulonephritis asks how they will know the child is improving. Which is the best response?
- A. Your child's urine output will increase and the urine will become less tea-colored.
- B. Your child will rest more comfortably as lab values normalize.
- C. Your child's appetite will decrease.
- D. Your child's lab values will become more normal.
Correct Answer: A
Rationale: An increase in urine output and a return to normal urine color are clear, observable signs of improvement in glomerulonephritis.
An infant has been pronounced dead from sudden infant death syndrome (SIDS) in the emergency department. Which is an appropriate question to ask the parents?
- A. "Did you hear the infant cry out?"
- B. "Why didn't you check on the infant earlier?"
- C. "What time did you find the infant?"
- D. "Was the head buried in a blanket?"
Correct Answer: C
Rationale: This is an appropriate question to ask the parents because determining the time the infant was found is important for investigating the circumstances surrounding the sudden infant death syndrome (SIDS) event. Understanding the timeline can help healthcare providers gather valuable information to determine the cause of death and evaluate any potential contributing factors. This question also allows the healthcare team to better understand the sequence of events leading up to the tragic outcome and offer support to the grieving parents. Asking about the time the infant was found is non-accusatory and focuses on gathering relevant details for the medical evaluation.
