. A client is admitted to the health care facility for evaluation for Addison's disease. Which laboratory test result best supports a diagnosis of Addison's disease?
- A. Blood urea nitrogen (BUN) level of
- B. Serum sodium level of 134 mEq/L
- C. Serum potassium level of 5.8 mEq/L
- D. Blood glucose level of 90 mg/dl
Correct Answer: C
Rationale: Addison's disease, also known as adrenocortical insufficiency, is characterized by a deficiency in adrenal cortex hormones, particularly glucocorticoids and mineralocorticoids. One of the characteristic findings in Addison's disease is hyperkalemia, which is an elevated serum potassium level. This is due to the lack of aldosterone production by the adrenal glands, leading to decreased potassium excretion by the kidneys. Therefore, a serum potassium level of 5.8 mEq/L would best support a diagnosis of Addison's disease among the given laboratory test results.

is type of hydrocephalus which there no obstructive to pass CSF but malformation of arachnoid villi :
- A. non communicating hydrocephalus
- B. communicating hydrocephalus
- C. obstructive hydrocephalus
- D. non of the above
Correct Answer: B
Rationale: Communicating hydrocephalus is a type of hydrocephalus where there is no obstruction to the passage of cerebrospinal fluid (CSF), but rather a malfunction or malformation of the arachnoid villi, which are responsible for the reabsorption of CSF. In communicating hydrocephalus, the flow of CSF within the ventricular system is disrupted, leading to an accumulation of fluid and resulting in increased intracranial pressure.
After the surgical incision has been clised and the anesthesia has wear-off, the patient is extubated and transferred to the postanesthesia care unit (PACU). Who is responsible for transferring the patient?
- A. Circulating nurse
- B. scrub nurse
- C. surgeon
- D. anesthesiologist
Correct Answer: D
Rationale: The anesthesiologist is responsible for transferring the patient to the postanesthesia care unit (PACU) after the surgical incision has been closed and the anesthesia has worn off. The anesthesiologist ensures that the patient is stable and ready for transfer, including assessing vital signs and overall condition. Due to their specialized training in anesthesia and perioperative care, the anesthesiologist is best equipped to manage the transition of care from the operating room to the PACU, where the patient will continue to be monitored closely during the immediate postoperative period.
The child who can transfers object from hand to hand and babbles has achieved the developmental age of
- A. 4 months

- C. 8 months
- D. 10 months
Correct Answer: B
Rationale: Transferring objects and babbling typically occur around 6 months.
A patient has end-stage dilated cardiomyopathy. He comes to the emergency department with dyspnea. He says he went to bed and awoke with a feeling of suffocation. He says it was frightening. Which of the ff. responses by the nurse is most appropriate?
- A. "You must have been dreaming."
- B. "Reclining decreases the heart's ability to pump blood." c."Sleeping increases heart rate, which increases the body's need for oxygen."
- C. "Reclining increases fluid returning to the heart, which builds up fluid in the lungs."
Correct Answer: C
Rationale: The most appropriate response by the nurse is option C, "Reclining increases fluid returning to the heart, which builds up fluid in the lungs." In a patient with end-stage dilated cardiomyopathy, reclining position can lead to increased fluid return to the heart due to the failing pump function. This can result in fluid backing up in the lungs, causing symptoms such as dyspnea or feeling of suffocation. By explaining this mechanism to the patient, the nurse can provide valuable information about the condition and the reason for the distressing symptoms experienced by the patient. It also highlights the importance of proper positioning to alleviate symptoms and improve the patient's comfort.
Which of the following dietary interventions prevents the precipitation of calcium renal stones?
- A. High fiber diet
- B. Increased protein intake
- C. High fluid intake
- D. Intake of zinc
Correct Answer: C
Rationale: High fluid intake is the dietary intervention that prevents the precipitation of calcium renal stones. By increasing fluid intake, particularly water, the urine gets diluted, thus reducing the concentration of substances that can lead to the formation of kidney stones, including calcium. Drinking enough water can also help to flush out any potential stone-forming minerals or substances before they have a chance to crystallize and form stones in the kidney. It is recommended to have an adequate fluid intake of around 2 to 3 liters per day to reduce the risk of calcium stone formation in the kidneys. High fiber diet, increased protein intake, and intake of zinc do not directly prevent the precipitation of calcium renal stones as effectively as maintaining high fluid intake.
