Oman Nurse Exam Prep OMSB Exam Questions & Answers 2026 (21–30)

Question 1

A patient has hemoglobin of 6.4 g/dL. The nurse expects to assess:

TheoryPractice · Accepted Answer

Severe anemia with pallor, fatigue, dyspnea, and tachycardia. Hemoglobin <7 g/dL indicates severe anemia; compensatory mechanisms produce tachycardia, pallor, dyspnea on exertion, and fatigue.

Question 2

A nurse is preparing to insert a urinary catheter in a female patient. Which action is performed FIRST after opening the sterile kit?

TheoryPractice · Accepted Answer

Don sterile gloves. After opening the sterile catheterization kit, the first action is to don sterile gloves to maintain the sterile field for all subsequent steps. Maintaining sterility throughout the procedure is essential to prevent catheter-associated UTIs (CAUTIs).

Question 3

Colostomy care includes which essential teaching point for the patient?

TheoryPractice · Accepted Answer

Change the appliance when it is one-third to one-half full to prevent leakage. Patients should empty the ostomy pouch when it is one-third to one-half full to prevent the weight from breaking the seal and causing leakage. Regular pouch maintenance prevents skin breakdown around the stoma.

Question 4

The nurse is teaching a patient about warfarin therapy. Which food should the patient be advised to consume consistently (not avoid entirely) due to its vitamin K content?

TheoryPractice · Accepted Answer

Green leafy vegetables (spinach, kale, broccoli). Patients on warfarin should maintain a CONSISTENT intake of vitamin K-rich foods (green leafy vegetables) rather than eliminating them. Sudden changes in vitamin K intake alter INR. Grapefruit and alcohol interact with warfarin metabolism and should be limited.

Question 5

The nurse is caring for a woman with placenta previa. Which assessment finding is MOST characteristic?

TheoryPractice · Accepted Answer

Painless bright red vaginal bleeding in the third trimester. Placenta previa presents with sudden, painless, bright red vaginal bleeding (without uterine tenderness) in the third trimester.

Question 6

What is the normal range for serum potassium (K⁺) in adults?

TheoryPractice · Accepted Answer

3.5–5.0 mEq/L. The normal serum potassium range in adults is 3.5–5.0 mEq/L. Values below 3.5 indicate hypokalemia; values above 5.0 indicate hyperkalemia, both of which can cause life-threatening cardiac arrhythmias.

Question 7

A patient is recovering from a hip replacement surgery. Which action by the nurse PREVENTS hip dislocation?

TheoryPractice · Accepted Answer

Maintain hip abduction using a wedge pillow, avoid adduction and internal rotation. Post-total hip replacement, dislocation is prevented by: avoiding hip flexion >90°, adduction (crossing legs), and internal rotation. Abduction wedge pillows maintain positioning. Patients should use raised toilet seats, avoid low chairs, and not bend to put on shoes.

Question 8

The nurse is performing a focused assessment on a patient complaining of dyspnea. Which assessment is the HIGHEST priority?

TheoryPractice · Accepted Answer

Measure oxygen saturation and auscultate breath sounds. Oxygen saturation and breath sounds directly assess respiratory function and guide immediate interventions for dyspnea.

Question 9

The nurse is administering a blood transfusion and the patient develops fever, chills, and back pain 30 minutes into the transfusion. The nurse's FIRST action is:

TheoryPractice · Accepted Answer

Stop the transfusion, keep the IV open with normal saline, notify the physician, and save the blood bag. Fever with chills and back pain during transfusion suggests a hemolytic or febrile non-hemolytic reaction; the transfusion must be stopped immediately, IV kept open with NS, physician notified, and blood bag sent to the lab.

Question 10

A patient arrives to the clinic with a snakebite on the right ankle. Priority nursing intervention includes:

TheoryPractice · Accepted Answer

Immobilize the limb at heart level, keep the patient calm, and transport immediately for antivenom evaluation. Snakebite management: DO NOT apply tourniquet (worsens tissue injury), DO NOT cut/suck the wound, DO NOT apply ice. Correct management: immobilize the limb slightly below heart level, keep patient calm to reduce heart rate and venom spread, remove constrictive items, and transport urgently. Antivenom is given in a hospital setting.
