When the nurse assesses the Cranial Nerve VII, which would the nurse ask the patient to perform? (Select all that apply)

Smile

Close eyes tightly

Shrug shoulders

Frown

Smell a flower

Answer and Explanation

Correct Answer : A,B,D

Choice A reason: Cranial Nerve VII (facial nerve) controls facial expression muscles. Asking the patient to smile tests the nerve’s motor function, specifically the zygomaticus muscles, which elevate the mouth corners, making this a correct assessment task for this nerve.

Choice B reason: Closing eyes tightly assesses Cranial Nerve VII’s motor function, specifically the orbicularis oculi muscle, which closes the eyelids. Weakness or asymmetry indicates potential facial nerve dysfunction, making this a correct task for evaluating this nerve.

Choice C reason: Shrugging shoulders tests Cranial Nerve XI (spinal accessory nerve), which innervates the trapezius and sternocleidomastoid muscles. This action is unrelated to Cranial Nerve VII’s facial motor functions, making it an incorrect choice for this assessment.

Choice D reason: Frowning assesses Cranial Nerve VII’s control over the corrugator supercilii and procerus muscles, which wrinkle the brow and depress the mouth. This task evaluates facial nerve function, making it a correct choice for the assessment.

Choice E reason: Smelling a flower tests Cranial Nerve I (olfactory nerve), responsible for smell sensation. This is unrelated to Cranial Nerve VII’s motor functions for facial expressions, making it an incorrect task for assessing this nerve.

Correct Answer is A

Explanation

Choice A reason: To calculate the dose, divide the ordered 180 mg by the concentration of 250 mg per 5 ml: (180 mg ÷ 250 mg) × 5 ml = 0.72 × 5 = 3.6 ml. This precise calculation ensures the correct amount of Dilantin is administered, matching the provider’s order.

Choice B reason: A 4.5 ml dose would deliver 225 mg (4.5 ml × 250 mg/5 ml), exceeding the ordered 180 mg. This overdose could increase the risk of toxicity, as Dilantin has a narrow therapeutic range, making this an incorrect choice.

Choice C reason: A 5 ml dose delivers 250 mg (5 ml × 250 mg/5 ml), significantly more than the ordered 180 mg. This excessive dose could lead to adverse effects like ataxia or nystagmus, rendering this choice incorrect for the prescribed amount.

Choice D reason: A 7 ml dose would provide 350 mg (7 ml × 250 mg/5 ml), far exceeding the ordered 180 mg. Such a high dose could cause severe toxicity, including neurological symptoms, making this an inappropriate and unsafe choice.

A. Pyelonephritis B. Cholecystitis C. gastric ulcer D. Pancreatitis

Correct Answer is A

Explanation

Choice A reason: Costovertebral angle tenderness is a classic sign of pyelonephritis, indicating kidney infection or inflammation. Percussing this area elicits pain in renal conditions, making it the correct condition to assess for tenderness.

Choice B reason: Cholecystitis causes pain in the right upper quadrant, not the costovertebral angle. Kidney-related pyelonephritis is linked to this tenderness, so this is incorrect for the assessment focus.

Choice C reason: Gastric ulcers cause epigastric pain, not costovertebral tenderness, which is renal-specific. Pyelonephritis is the condition associated with this sign, so this is incorrect for the suspected condition.

Choice D reason: Pancreatitis presents with abdominal pain, not costovertebral angle tenderness, which indicates kidney issues. Pyelonephritis is the relevant condition, so this is incorrect for the assessment.
