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.

Place in order the expected sequence of fine motor developmental milestones for an infant beginning with the first milestone achieved and ending with the last milestone achieved. Provide answer using lowercase letters separated by commas (e.g., a, b, c, d, e).
- A. Voluntary palmar grasp
- B. Reflex palmar grasp
- C. Puts objects into a container
- D. Neat pincer grasp
Correct Answer: B
Rationale: 1. Reflex palmar grasp (B) - Infants are born with a reflex called the palmar grasp reflex, which means they automatically close their fingers around an object placed in their palm. This reflex typically disappears around 3-4 months of age.

Bryce is a child diagnosed with coarctation of aorta. While assessing him, Nurse Zach would expect to find which of the following?
- A. Squatting posture
- B. Absent or diminished femoral pulses
- C. Severe cyanosis at birth
- D. Cyanotic ("tet") episodes 46
Correct Answer: B
Rationale: Coarctation of the aorta is a congenital heart defect where there is a narrowing of the aorta, usually near the insertion of the ductus arteriosus. This narrowing can lead to decreased blood flow to the lower body. A common finding in a child with coarctation of the aorta is absent or diminished femoral pulses due to the obstruction of blood flow through the narrowed aorta. Other symptoms may include high blood pressure in the arms, weak lower body pulses, and heart murmur. Squatting posture, severe cyanosis at birth, and cyanotic ("tet") episodes are not typically associated with coarctation of the aorta.
A 3-year-old female is hospitalized for a femur fracture. As her nurse, what nursing action would help foster the child's sense of autonomy?

Justine is admitted to the pediatric unit due to the occurrence of diabetic ketoacidosis signaling a new diagnosis of diabetes. The diabetes team explores the cause of the episode and take steps to prevent a recurrence. Diabetic ketoacidosis (DKA) results from an excessive accumulation of which of the following?
- A. Sodium bicarbonate from renal compensation
- B. Potassium from cell death
- C. Glucose from carbohydrate metabolism
- D. Ketone bodies from fat metabolism
Correct Answer: D
Rationale: Diabetic ketoacidosis (DKA) is a serious complication of diabetes that occurs when there is not enough insulin in the body. In the absence of sufficient insulin, the body is unable to use glucose for energy, leading to the breakdown of fats for fuel. This results in the excessive production of ketone bodies, specifically acetoacetate and beta-hydroxybutyrate. As the ketone bodies accumulate in the blood, they lower the blood pH, leading to acidosis. This is what causes the characteristic symptoms of DKA, such as fruity breath, deep rapid breathing, and abdominal pain. Therefore, the excessive accumulation of ketone bodies from fat metabolism is the primary cause of diabetic ketoacidosis.
