Question 1

What is the correct angle for intramuscular injection in the vastus lateralis muscle?

Accepted Answer

90 degrees

Answer

Intramuscular injections are administered at a 90-degree angle to ensure the medication reaches muscle tissue rather than subcutaneous fat. The vastus lateralis is a common IM site for adults and infants.

Question 2

A patient has a nasogastric tube. Before administering medication, what must the nurse confirm?

Accepted Answer

Tube placement in the stomach

Answer

Confirming NG tube placement before each use prevents aspiration pneumonia from accidental pulmonary medication instillation. Methods include pH testing of aspirate, X-ray confirmation, or auscultation.

Question 3

Which sign/symptom indicates a fluid volume deficit (dehydration)?

Accepted Answer

Decreased skin turgor and dry mucous membranes

Answer

Decreased skin turgor and dry mucous membranes are classic signs of dehydration due to reduced extracellular fluid. Bounding pulse, hypertension, periorbital edema, and distended neck veins indicate fluid excess.

Question 4

What is the purpose of using a draw sheet when repositioning a patient?

Accepted Answer

To reduce friction and shear on the skin during repositioning

Answer

A draw sheet reduces friction and shear forces on vulnerable skin during repositioning, protecting against pressure injury formation. Friction and shear are major contributing factors to skin breakdown in immobile patients.

Question 5

What is the recommended frequency for repositioning bedridden patients to prevent pressure ulcers?

Accepted Answer

Every 2 hours

Answer

Evidence-based guidelines recommend repositioning immobile patients every 2 hours to relieve sustained pressure on bony prominences, restore tissue perfusion, and prevent pressure ulcer formation.
