The nurse understands that for the parathyroid hormone to exert its effect, what must be present?
- A. Decreased phosphate level
- B. Functioning thyroid gland
- C. Adequate vitamin D level
- D. Increased calcium level
Correct Answer: D
Rationale: Parathyroid hormone (PTH) is released by the parathyroid glands in response to low calcium levels in the blood. Its primary function is to regulate calcium and phosphorus levels in the body. When calcium levels in the blood are low, PTH is released, leading to increased calcium levels by stimulating the release of calcium from the bones, increasing calcium absorption in the intestines, and promoting calcium reabsorption in the kidneys. Therefore, for PTH to exert its effect, increased calcium levels must be present.

Several days before admission, a client reports finding a small lump in the left breast near the nipple. What should the nurse tell the client to do?
- A. Inform the physician immediately
- B. Check the area after the next menstrual
- C. Squeeze the nipple to check for period
- D. Put a heating pad on the area to reduce inflammation

Finding a lump in the breast near the nipple can be concerning as it might indicate a potential issue like breast cancer. Prompt assessment by a healthcare provider is essential for proper evaluation and timely intervention if needed. It is crucial not to delay seeking medical attention for any breast abnormalities to ensure early detection and management of any possible health conditions.
Between 2-6 months of life, all are true about infant sleep EXCEPT

What is the earliest age at which a satisfactory radial pulse can be taken in children?
- A. 1 year
- B. 2 years
- C. 3 years
- D. 6 years
Correct Answer: A
Rationale: A satisfactory radial pulse can be taken in children as young as 1 year old. The radial pulse is commonly checked in the wrist and is a valuable indicator of cardiac function. Children as young as 1 year old can have a palpable radial pulse, allowing healthcare providers to assess their heart rate and rhythm. It is important to be gentle when palpating a pulse in young children to avoid causing discomfort or distress.
The nurse is assessing a 3-month-old during a well-baby visit. Which of the following findings would warrant the nurse to recommend that the baby have an ultrasound for a possible diagnosis of developmental dysplasia of the hip (DDH)?
- A. Bilateral plantar flexion
- B. Unequal knee heights
- C. Bilateral polydactyly
- D. Positive Babinski test 113
Correct Answer: B
Rationale: Developmental dysplasia of the hip (DDH) is a condition where the hip joint does not develop normally. It is important to detect DDH early in infants as it can lead to long-term hip problems. One of the key physical exam findings that may suggest DDH is unequal knee heights when the infant's legs are flexed. This is known as the Galeazzi sign, and it can indicate hip dysplasia or dislocation. Therefore, if a nurse observes this finding during an assessment of a 3-month-old infant, it would warrant recommending an ultrasound to further evaluate for possible DDH. Bilateral plantar flexion, bilateral polydactyly, and a positive Babinski test are not typically associated with DDH.
