Question 1 of 5
Parents of a 6-month-old breastfed baby ask the nurse about increasing the baby's diet. Which of the following should be added first?
Correct Answer: A
Rationale: The correct answer is 'Cereal.' The guidelines of the American Academy of Pediatrics recommend introducing one new food at a time, starting with strained cereal. Cereal is often recommended as a first solid food for infants due to its soft texture and iron-fortified properties, which are important for the baby's development. Eggs and meat are common allergenic foods and are usually introduced later. Juice is not recommended for infants under 1 year old due to its high sugar content and lack of nutritional value compared to whole fruits.
Question 2 of 5
Why are subdural hemorrhages more common in the elderly?
Correct Answer: C
Rationale: Subdural hemorrhages are more common in the elderly due to cerebral atrophy resulting from the natural aging process. This atrophy can lead to the stretching of bridging veins, making them more fragile and prone to tearing even with minor trauma. While increased anticoagulant use and a higher risk of falls are common in the elderly, brain atrophy plays a more direct role in the increased incidence of subdural hemorrhages. Inconsistent caregiving, on the other hand, is not a direct cause of subdural hemorrhages but may impact the overall management and outcome of such cases.
Question 3 of 5
The infection control nurse is assigned to a patient with osteomyelitis related to a heel ulcer. The wound is 5cm in diameter and the drainage saturates the dressing so that it must be changed every hour. What is her priority intervention?
Correct Answer: A
Rationale: The priority intervention for a patient with osteomyelitis related to a heel ulcer, with a wound that saturates the dressing every hour, is to place the patient under contact precautions. Contact precautions are essential when managing infectious wounds to prevent the spread of infection to healthcare workers, other patients, and visitors. Strict aseptic technique (
Choice
B) should always be used with wound care but is secondary to implementing contact precautions in this scenario. Placing another dressing (
Choice
C) or elevating the patient's leg (
Choice
D) may be necessary but do not address the immediate need for infection control measures.
Question 4 of 5
A physician suspects a patient may have pancreatitis. Which of the following tests would be most appropriate to diagnose this condition?
Correct Answer: C
Rationale:
To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis.
Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis.
Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis.
Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.
Question 5 of 5
A client using an intraaural hearing aid experiences whistling after placement. What is the nurse's next action?
Correct Answer: A
Rationale: An intraaural hearing aid, also known as an in-the-ear hearing aid, is placed in the ear canal. Whistling after placement indicates improper positioning of the device. The correct action for the nurse is to try repositioning the hearing aid to eliminate the whistling. Changing the batteries is not necessary for addressing whistling. Removing the device to clean it is not the immediate action needed for whistling. Notifying the physician is premature without attempting to reposition the hearing aid first.
