A nurse is caring for a child who has nosebleed. Which of the following actions should the nurse take?

Place the child in a sitting position and tilt her head back.

Apply ice at the opening of the nares for 5 min and then re-check for bleeding.

Have the child sit with her head tilted forward and hold pressure on her nose for 10 min.

Place the child in a supine position with a pillow under her head.

Answer and Explanation

The Correct Answer is C

A. Place the child in a sitting position and tilt her head back: Tilting the head back risks blood aspiration or swallowing, which can cause nausea or vomiting.

B. Apply ice at the opening of the nares for 5 minutes and then re-check for bleeding: Ice may help, but direct pressure is the first-line intervention.

C. Have the child sit with her head tilted forward and hold pressure on her nose for 10 min: This is the appropriate action to stop bleeding and prevent blood from entering the airway or stomach.

D. Place the child in a supine position with a pillow under her head: This position is unsafe as it can lead to blood pooling in the back of the throat.

Correct Answer is D

Explanation

A. Used in the treatment of cystic fibrosis to help break up thick secretions: Prednisone is not used to treat cystic fibrosis. Drugs like dornase alfa are used for this purpose, not corticosteroids.

B. Used for the prophylactic treatment of asthma/allergies: Prednisone is not typically used for the prophylaxis of asthma or allergies. It may be used for acute exacerbations but is not for long-term control.

C. Used to treat hypertension and edema: Prednisone is not used to treat hypertension or edema directly. Corticosteroids like prednisone can sometimes increase blood pressure and cause fluid retention as side effects.

D. Used to treat inflammation and swelling: Prednisone is a corticosteroid used to reduce inflammation and swelling in conditions such as asthma, arthritis, and other inflammatory disorders.

A. Transcranial doppler B. Sickle solubility test C. Complete blood count D. Hemoglobin electrophoresis

Correct Answer is D

Explanation

A. Transcranial doppler: This test is used to assess blood flow in the brain and is often used for children with sickle cell disease to evaluate the risk of stroke. It is not used to distinguish between sickle cell disease and trait.

B. Sickle solubility test: This test is used to identify sickling in red blood cells, which can indicate sickle cell disease, but it does not differentiate between sickle cell disease and sickle cell trait.

C. Complete blood count (CBC): While a CBC can provide information about anemia and red blood cell characteristics, it cannot differentiate between sickle cell disease and sickle cell trait.

D. Hemoglobin electrophoresis: This test is the gold standard for diagnosing sickle cell disease and trait. It separates different types of hemoglobin based on their electrical charge, allowing for the identification of hemoglobin S (sickle hemoglobin), which distinguishes between sickle cell disease (homozygous) and sickle cell trait (heterozygous).
