Which of the following is an expected finding during assessment of the older adult?

Heart disease remains the leading cause of death worldwide, but many cases are preventable through lifestyle modifications and early risk-factor management. Nurses play a critical role in educating patients about strategies to reduce their risk of cardiovascular disease.

Rationale for correct answer:

2. Talk with your health care provider about taking a daily low dose of aspirin: Daily low-dose aspirin therapy may be beneficial for certain individuals at high risk for heart disease (e.g., those with a history of heart attack or stroke).

3. Work with your health care provider to develop a regular exercise program: Regular physical activity helps reduce blood pressure, control weight, improve cholesterol levels, and boost cardiovascular fitness.

4. Limit saturated and trans fats, sodium, red meats, sweets, and sugar-sweetened beverages: A heart-healthy diet includes reducing intake of saturated and trans fats (which raise LDL cholesterol), processed foods high in sodium, red meat, and added sugars.

5. Review strategies to encourage the patient to quit smoking: Smoking is a major modifiable risk factor for heart disease. Nurses should assess readiness to quit, provide resources such as counseling or nicotine replacement, and refer to cessation programs.

Rationale for incorrect answer:

1.Add salt to every meal: Excessive sodium intake is associated with high blood pressure, a major risk factor for heart disease and stroke. Rather than adding salt, patients should be encouraged to limit sodium intake to <2,300 mg/day (or lower if hypertensive).

Take home points

• Heart disease prevention focuses on lifestyle changes, such as diet, exercise, smoking cessation, and individualized risk assessments (e.g., aspirin use).
• Patient education should emphasize what to limit (e.g., sodium, fats, smoking) and what to increase (e.g., activity, healthy food choices) to promote cardiovascular health.

The cranial nerves (CN I–XII) emerge directly from the brain and brainstem and control various motor, sensory, and parasympathetic functions of the head, neck, and some thoracic organs. During a comprehensive neurological assessment, the nurse must test these nerves to identify signs of neurologic dysfunction.

Rationale for correct answers:

1.XII Hypoglossal -e. Position of the tongue

The hypoglossal nerve controls the motor movement of the tongue. During assessment, the client is asked to stick out the tongue, and deviation or weakness indicates impairment of CN XII.

2. V Trigeminal -a. Motor innervation to the jaw

The trigeminal nerve has both motor and sensory components. Motor function includes muscles of mastication (chewing). The nurse assesses jaw movement and strength.

3. VI Abducens -b. Lateral movement of the eyeballs

The abducens nerve controls the lateral rectus muscle, which moves the eye laterally (abduction). Inability to look outward may suggest CN VI palsy.

4. IV Trochlear -d. Downward, inward eye movements

The trochlear nerve controls the superior oblique muscle, responsible for downward and inward eye movement. Difficulty with this motion may lead to vertical diplopia (double vision).

5. X Vagus -c. Sensation of the pharynx

The vagus nerve provides sensory innervation to the pharynx and larynx, and also has motor and parasympathetic functions. It plays a role in swallowing, speech, and the gag reflex.

Take home points

Each cranial nerve has specific motor, sensory, or both functions, and testing them individually helps identify the location and extent of neurological impairment.

• Cranial nerves IV (Trochlear), VI (Abducens), and III (Oculomotor) are especially important for eye movement coordination.
• CN V (Trigeminal) and XII (Hypoglossal) focus on facial sensation/mastication and tongue movement, respectively.
