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.
Which term refers to a newborn born before completion of week 37 of gestation, regardless of birth weight?
- A. Postterm
- B. Preterm
- C. Low birth weight
- D. Small for gestational age
Correct Answer: B
Rationale: The term "preterm" refers to a newborn born before completion of week 37 of gestation, regardless of birth weight.

It is important for healthcare providers to closely monitor preterm infants to ensure they receive the proper care and support for their development.
a school-age child is admitted in vaso-occlusive sickle cell crisis. the child's care should include which of the following?
- A. correction of acidosis.
- B. adequate hydration, pain management.
- C. pain management, administration of heparin.
- D. adequate oxygenation, replacement of factor viii
Correct Answer: B
Rationale: In a vaso-occlusive sickle cell crisis, it is crucial to focus on adequate hydration and pain management. Hydration is essential to prevent further sickling of red blood cells, which can exacerbate tissue damage and pain. Pain management is a key aspect of care as vaso-occlusive crises often cause severe pain that requires prompt and effective treatment. Administering heparin is not indicated in a vaso-occlusive sickle cell crisis as it is primarily used for conditions like deep vein thrombosis. Correcting acidosis and replacing factor VIII are also not typically part of the management of a vaso-occlusive sickle cell crisis.
A client with cancer is scheduled for radiation therapy. The nurse knows that radiation at any treatment site may cause a certain adverse effect. Therefore, the nurse should prepare the client to expect:
- A. Hair loss.
- B. Fatigue.
- C. Stomatitis.
- D. Vomiting.
Correct Answer: A
Rationale: Radiation therapy works by targeting rapidly dividing cells in the body, which includes not only cancer cells but also healthy cells. Hair loss, also known as alopecia, is a common side effect of radiation therapy because the hair follicles are fast-growing cells that can be affected by the radiation. The extent of hair loss can vary depending on the dose and area of the body being treated. It is essential for nurses to prepare clients for the possibility of hair loss during radiation therapy and provide support and information on managing this side effect.
At the time of birth, what is the grayish white, cheeselike substance that normally covers the newborn's skin called?
- A. Miliaria
- B. Meconium
- C. Amniotic fluid
- D. Vernix caseosa
Correct Answer: D
Rationale: Vernix caseosa is the grayish white, cheeselike substance that normally covers a newborn's skin at the time of birth. It is a natural substance produced by the baby's skin glands while in the womb. Vernix caseosa helps protect the baby's delicate skin from the amniotic fluid in the uterus and acts as a moisturizer as well. It also has antimicrobial properties, providing a barrier against infection. After birth, healthcare providers typically wipe off or gently wash the vernix from the baby's skin during the first bath.
