What does the surgical closure of the ductus arteriosus do?
- A. Stop the loss of unoxygenated blood to the systemic circulation
- B. Decrease the edema in legs and feet
- C. Increase the oxygenation of blood
- D. Prevent the return of oxygenated blood to the lungs
Correct Answer: A
Rationale: The ductus arteriosus is a fetal blood vessel that allows blood to bypass the lungs while in utero. After birth, the ductus arteriosus should close to redirect blood flow through the lungs for oxygenation. Surgical closure of the ductus arteriosus is performed to prevent the shunting of unoxygenated blood from the pulmonary artery to the aorta, therefore stopping the loss of unoxygenated blood to the systemic circulation. This helps to ensure that oxygenated blood is properly circulated to the body tissues and organs.
A 14-year-old boy is being admitted to the hospital for an appendectomy. Which roommate should the nurse assign with this patient?
- A. A 4-year-old boy post-appendectomy surgery
- B. A 6-year-old boy with pneumonia
- C. A 15-year-old boy admitted with a vasoocclusive sickle cell crisis
- D. A 12-year-old boy with cellulitis
Correct Answer: C
Rationale: The nurse should assign the 14-year-old boy recovering from an appendectomy to Roommate C, the 15-year-old boy admitted with a vasoocclusive sickle cell crisis. This decision is based on providing similar age groups and conditions for mutual support and understanding. Both patients are teenagers and are experiencing health challenges that involve pain management and supportive care. This pairing can offer emotional and social benefits as they navigate their hospital stay together. It is important to consider factors like age, condition, and potential social interactions when assigning roommates in a healthcare setting to promote a positive environment for healing and recovery.
Why must clients who will undergo diagnostic skin test avoid taking antihistamine or cold preparations for at least 48-72 hrs before testing?
- A. Antihistamines may increase the potential for excessive bleeding
- B. Antihistamines may aggravate the allergic reaction
- C. Antihistamines may increase the potential for false negative results
- D. Antihistamines may cause wheezing
Correct Answer: C
Rationale: Antihistamines are medications commonly used to relieve symptoms of allergies, including itching, sneezing, and hives. When a client undergoing a diagnostic skin test for allergies takes antihistamines, it can suppress the body's allergic response, leading to false negative results. This means that the test may not accurately identify all the substances to which the client is allergic, potentially leading to a misdiagnosis. To ensure the accuracy of the skin test, clients are advised to avoid taking antihistamines or cold preparations for at least 48-72 hours before the testing to allow their body to exhibit the appropriate allergic response.
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.
After a 3- month trail of dietary therapy, a client with type2 diabetes mellitus still has blood glucose levels above 180 mg/dl. The physician adds glyburide (DiaBeta), 2.5 mg P.O. daily, to the treatment regimen. The nurse should instruct the client to take glyburide:
- A. 30 minutes before breakfast
- B. 30 minutes after dinner.
- C. in the midmorning
- D. at bedtime.
Correct Answer: D
Rationale: Glyburide (DiaBeta) is a sulfonylurea medication used to treat type 2 diabetes mellitus by stimulating the pancreas to release more insulin. Taking glyburide at bedtime is recommended because it helps to ensure that the medication's peak action aligns with the natural rise in blood glucose levels in the early morning hours, which can help control fasting blood glucose levels. Additionally, taking glyburide in the evening reduces the risk of hypoglycemia during the day when the client may be more active and less likely to monitor blood glucose levels closely.
