A nurse is preparing to measure the visual acuity of a client. The nurse should recognize that which nerve should be assessed?

Answer and Explanation

The Correct Answer is A

A) II:
This is the correct answer. The optic nerve (cranial nerve II) is responsible for visual acuity, as it transmits visual information from the retina to the brain. When assessing visual acuity, the nurse is evaluating the function of the optic nerve, which is responsible for the sense of vision. Therefore, cranial nerve II should be assessed during a visual acuity exam.

B) I:
This is incorrect. The olfactory nerve (cranial nerve I) is responsible for the sense of smell, not vision. Visual acuity is not related to the olfactory nerve, so it is not involved in this type of assessment.

C) VI:
This is incorrect. The abducens nerve (cranial nerve VI) controls the lateral rectus muscle of the eye, which is responsible for outward eye movement. While cranial nerve VI plays a role in eye movement, it is not directly involved in measuring visual acuity, which pertains to the function of the optic nerve.

D) IV:
This is incorrect. The trochlear nerve (cranial nerve IV) controls the superior oblique muscle, which helps with eye movement, specifically downward and inward eye movements. This nerve is not involved in measuring visual acuity.

Correct Answer is A

Explanation

A) The atria contract toward the end of diastole and push the remaining blood into the ventricles:
This is the correct definition of the atrial kick. The atrial kick refers to the contraction of the atria just before the ventricles contract, which occurs late in diastole. During this phase, the atria contract to push the remaining blood into the ventricles, ensuring that the ventricles are as filled as possible before the next ventricular contraction. This action contributes to about 20–30% of the ventricular filling, especially important in situations where the heart rate is fast, as there may be less time for passive filling during diastole.

B) Contraction of the atria at the beginning of diastole can be felt as a click:
This statement is incorrect. Atria contract at the end of diastole, not the beginning. The atrial contraction is not typically felt as a "click." If there is a "click" sound, it could indicate an abnormal heart valve sound, such as from a mitral valve prolapse, rather than the normal atrial contraction. The atrial kick itself is not associated with any audible click but may be heard as part of the S4 heart sound, especially in conditions with stiff ventricles (such as hypertension or heart failure).

C) The ventricles contract during systole and attempt to push against closed atria:
This is not an accurate description of the atrial kick. During systole, the ventricles contract and push blood into the aorta and pulmonary artery through the open semilunar valves, not against the atria. The atrial kick is a part of diastole, not systole, and involves the atria pushing blood into the ventricles, not the ventricles pushing against the atria.

D) Atrial kick is the pressure exerted against the atria as the ventricles contract during systole:
This description is incorrect. The atrial kick occurs when the atria contract near the end of diastole, not during systole. During systole, the ventricles contract and pump blood out of the heart, but this is not related to the atrial kick. Instead, the atrial kick is the contribution of atrial contraction to the final phase of ventricular filling, just before the ventricles contract.

A. Client's oral temperature is 38.40 C (101.2° F). B. Client reports the rash on their back is itchy. C. Client reports nausea following, administration of pain medication. D. Client has a vesicular rash on their upper back. E. Client reports dull, aching pain in lower right call.

Correct Answer is ["B","C","E"]

Explanation

A) Client's oral temperature is 38.4°C (101.2°F):
This is objective data, as it is a measurable, observable finding obtained through direct assessment (in this case, using a thermometer). Objective data are facts or measurements that can be verified or observed by the healthcare provider.

B) Client reports the rash on their back is itchy:
This is subjective data, as it is based on the client's personal experience and report. The feeling of itchiness cannot be directly measured or observed by the nurse; it is something the client experiences and describes. Subjective data include symptoms, sensations, or feelings reported by the client.

C) Client reports nausea following administration of pain medication:
This is subjective data. Nausea is a symptom that the client reports experiencing, which cannot be objectively measured or directly observed by the nurse. It is based on the client's perception and report, making it subjective.

D) Client has a vesicular rash on their upper back:
This is objective data. The rash is something the nurse can observe and describe. Objective data include observable facts, such as physical exam findings, lab results, or diagnostic test results.

E) Client reports dull, aching pain in lower right calf:
This is subjective data, as pain is a sensation that the client experiences and describes. The intensity, location, and type of pain (dull, aching) are subjective experiences that only the client can report.
