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 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.
A 16-year-old mother complaining she feels unhappy living with her husband and his family. The most appropriate action is
- A. refer her to an obstetrician
- B. explain the way of milk expression
- C. apply Edinburgh postnatal depression scale
- D. advise her on milk engorgement
Correct Answer: C
Rationale: The Edinburgh Postnatal Depression Scale is a screening tool for postnatal depression which might address her unhappiness.

The mother of a child with a congenital cardiac defect asks the nurse why her child squats after exertion. The nurse should reply that this position:
- A. Reduces muscle aches
- B. Increases cardiac efficiency
- C. Enhances the pull of gravity
- D. Decreases blood volume in the extremities
Correct Answer: B
Rationale: The position of squatting after exertion increases cardiac efficiency in children with congenital cardiac defects, specifically those with Tetralogy of Fallot. By squatting, the child decreases systemic vascular resistance and increases systemic venous return, which helps to enhance cardiac output by improving blood flow to the lungs. This position allows for better oxygenation of the blood and helps alleviate cyanosis in children with Tetralogy of Fallot.
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.
