Nursing Elites

1. When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?

• A. Iris
• B. Cornea
• C. Optic disc
• D. Conjunctiva

Correct answer: C

Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope. Therefore, the correct answer is the optic disc. Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.

2. A pregnant client tells the nurse that she has a 2-year-old child at home and expresses concern about how the toddler will adapt to a newborn infant being brought into the home. Which statement is the most appropriate response for the nurse to make to the client?

• A. If your 2-year-old becomes angry or jealous, you should consider preparing the child for the new sibling rather than seeking psychological intervention.
• B. Don't worry; every 2-year-old may need time to adjust to a newborn sibling.
• C. Even though a 2-year-old may have little perception of time, any changes in sleeping arrangements for the newborn should be made several weeks before birth.
• D. A 2-year-old toddler focuses on exploring the environment, but it's important to prepare the child for the new sibling.

Correct answer: C

Rationale: The correct response by the nurse is, 'Even though a 2-year-old may have little perception of time, any changes in sleeping arrangements for the newborn should be made several weeks before birth.' Toddlers are generally unaware of the changes during pregnancy and may not understand the impending arrival of a new sibling. It is essential to prepare the child gradually for the new baby's arrival by making any necessary changes in sleeping arrangements beforehand. Expecting a young child to immediately welcome a new sibling without prior preparation is unrealistic. Option A is incorrect as suggesting psychological intervention prematurely is not appropriate. Option B is incorrect as assuming all 2-year-olds would immediately welcome a newborn is unrealistic. Option D is incorrect as dismissing the concerns without addressing the need for preparation is not appropriate in this situation.

3. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

4. A 65-year-old female client is experiencing postmenopausal bleeding. Which type of physician should this client be encouraged to see?

• A. a radiologist
• B. a gynecologist
• C. a physiatrist
• D. an oncologist

Correct answer: B

Rationale: A gynecologist is the appropriate physician for this scenario as they specialize in treating and managing diseases of the female reproductive system, including postmenopausal bleeding. Postmenopausal bleeding can indicate serious conditions such as endometrial cancer, which a gynecologist can evaluate and manage. A radiologist primarily evaluates X-rays and imaging studies, not directly involved in managing gynecological issues. A physiatrist is a specialist in physical medicine and rehabilitation, not related to gynecological concerns. An oncologist specializes in diagnosing and treating cancer, which is not the primary concern in this case of postmenopausal bleeding.

5. How does the family carry out its health care functions?

• A. The family provides very little preventive health care to its members at home.
• B. The family provides preventive health care to its members at home.
• C. The family pays for most health services.
• D. The family decides when and where to hospitalize its members.

Correct answer: B

Rationale: Families play a crucial role in providing preventive health care to their members at home. This includes activities such as promoting healthy lifestyles, ensuring vaccinations, scheduling regular check-ups, and intervening early when health issues arise. Therefore, the correct answer is that the family provides preventive health care to its members at home. Choices A, C, and D are incorrect because families are expected to actively engage in preventive health care practices rather than providing very little preventive care, solely paying for health services, or making hospitalization decisions. The focus is on the proactive role of families in maintaining the health of their members.
