Arvic who is diagnosed with diabetes mellitus type 1 displays symptoms of hypoglycemia; which of the following actions should the nurse instruct the parents?
- A. Give the child honey (simple sugar).
- B. Give the child milk (complex sugar).
- C. Contact the healthcare provider before doing anything.
- D. Give the child nothing by mouth.
Correct Answer: A
Rationale: In a patient with diabetes mellitus type 1 showing symptoms of hypoglycemia, it is important to take immediate action to raise their blood sugar levels. The best way to quickly raise blood sugar levels in a hypoglycemic patient is by giving them a simple sugar, such as honey, fruit juice, or glucose tablets. These sugars are rapidly absorbed into the bloodstream, providing a quick source of energy to the body. Milk, which was mentioned in option B, contains complex sugars and fats that may delay the increase in blood sugar levels. It is crucial to act promptly in a hypoglycemic situation, as untreated hypoglycemia can lead to serious complications, including seizures and loss of consciousness. Contacting the healthcare provider before giving treatment, as in option C, may cause dangerous delays in addressing the low blood sugar situation. Option D, giving the child nothing by mouth, is not appropriate in this scenario as it can wors
A 1-year-old child develops right eye ptosis, miosis, and loss of sweating; you suspect neuroblastoma. The MOST valuable investigation to confirm the diagnosis is
- A. CT scan of the neck and chest
- B. CT scan of the abdomen
- C. CT scan of the brain
- D. magnetic resonance imaging (MRI) of the brain
Correct Answer: A
Rationale: CT scan of the neck and chest can help identify a primary neuroblastoma mass in the adrenal gland or sympathetic chain.
Which of the ff. would the nurse explain to the patient is indicated by a Snellen chart finding 20/80?
- A. The eye can see at 80 feet what the normal eye can see at 20 feet.
- B. The eye can see at 20 feet what the normal eye can see at 80 feet.
- C. The eye can see four times what the normal eye can see.
- D. The eye sees normally.
Correct Answer: A
Rationale: The Snellen chart is a chart used to measure visual acuity. The numbers in a Snellen fraction indicate the distance from which a person with normal eyesight can see the letters on the chart. In the case of 20/80, this means that the person can see at 80 feet what a person with normal eyesight can see at 20 feet. So, option A is correct as it accurately explains what is indicated by a Snellen chart finding of 20/80.
A 12-month-old boy weighed 8 lb 2 oz at birth. What weight should the nurse expect him to be now?
- A. 16 lb 4 oz
- B. 20 lb 5 oz
- C. 24 lb 6 oz
- D. 32 lb 8 oz
Correct Answer: C
Rationale: Infants typically triple their birth weight by 12 months. For an 8-lb infant, that would be approximately 24 lb.
A client with severe head trauma sustained in a car accident is admitted to the intensive care unit. Thirty six-hours later, the client's urine output suddenly rises above 200mL/hour, leading the nurse to suspect diabetes insipidus. Which laboratory findings support the nurse's suspicion of diabetes insipidus?
- A. Above-normal urine and serum osmolality levels
- B. Below-normal urine and serum osmolality levels
- C. Above-normal urine osmolality level, below-normal serum osmolality level
- D. Below- normal urine osmolality level, above-normal serum osmolality level
Correct Answer: B
Rationale: Diabetes insipidus is a condition characterized by the inability of the kidneys to adequately concentrate urine, leading to excessive dilute urine production. In diabetes insipidus, both urine and serum osmolality levels are typically below normal due to the dilution of urine. When urine output suddenly rises above 200mL/hour in a client with severe head trauma, it may indicate diabetes insipidus, especially if the urine and serum osmolality levels are below normal. This abnormality in osmolality levels is due to the impaired ability of the kidneys to concentrate urine, resulting in decreased urine osmolality and subsequent dilution of the serum osmolality.
