The adrenal cortex is responsible for producing which substances?
- A. Glucocortocoids and androgens
- B. Mineralocortiroids and
- C. Catecholamines and epinephrine catecholamines
- D. Norepinephine and epinephrine
Correct Answer: A
Rationale: The adrenal cortex is the outer portion of the adrenal glands and is responsible for producing hormones known as corticosteroids. Within the corticosteroids, the adrenal cortex produces glucocorticoids (such as cortisol) which are involved in regulating metabolism and the immune response. Additionally, the adrenal cortex produces androgens which are male sex hormones, although they are present in both males and females. Therefore, the correct substances produced by the adrenal cortex are glucocorticoids and androgens (Choice A).

A community nurse will perform chest physiotherapy for Mrs. Dy every 3 hours. It is important for the nurse to:
- A. slap the chest wall gently
- B. use vibration techniques to move secretions from affected lung areas during the inspiration phase
- C. perform CPT at least two hours after meals
- D. plan apical drainage at the beginning of the CPT session
Correct Answer: C
Rationale: Performing chest physiotherapy (CPT) at least two hours after meals is important to prevent potential risks such as vomiting and aspiration. This timing allows for better tolerance of the procedure and decreases the likelihood of complications. By waiting at least two hours after meals, the nurse ensures that the patient's stomach is not full, reducing the risk of regurgitation during the chest physiotherapy session. This practice promotes the safety and well-being of the patient while undergoing this treatment.
The physician writes a "now" order for codeine 45 mg IM for a patient with thrombophlebitis. The nurse has on hand 60 mg/2 mL. Which of the ff. doses should be given?
- A. 1.45 mL c.1.75 mL
- B. 1.50 mL
- C. 2.15 mL
Correct Answer: B
Rationale: To determine how many milliliters of the medication should be given, it is important to first calculate the total amount of codeine required based on the physician's order. The physician ordered codeine 45 mg IM, and the available concentration is 60 mg/2 mL. To find out the appropriate dose to administer, you can set up a proportion:
What is the best method to obtain a urine sample in an 8-month-old being evaluated for a UTI?

What might you conclude if you notice a wide perineum and unequal gluteal and thigh folds when assessing a newborn?
- A. Osteogenesis imperfecta
- B. Torticollis
- C. Scoliosis
- D. Hip dysplasia
Correct Answer: D
Rationale: When assessing a newborn and noticing a wide perineum and unequal gluteal and thigh folds, it may signal the possibility of developmental dysplasia of the hip (DDH), also known as hip dysplasia. DDH is a condition where the hip joint does not properly form in newborns, leading to instability and potential dislocation. The wide perineum and unequal gluteal and thigh folds are physical signs that can be indicative of hip dysplasia. It is essential to diagnose and treat hip dysplasia early to prevent long-term complications like difficulty walking and osteoarthritis. Regular screening of newborns for hip dysplasia risk factors and physical exam findings is crucial for early detection and intervention.
