Nokea
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.

During a throat assessment, a healthcare provider asks a client to stick out their tongue and notices it protrudes in the midline. Which cranial nerve is being tested?
- A. Cranial nerve X
- B. Cranial nerve V
- C. Cranial nerve IX
- D. Cranial nerve XII
Correct Answer: D
Rationale: The correct answer is cranial nerve XII (hypoglossal nerve). When testing cranial nerve XII, the healthcare provider inspects the symmetry and movement of the tongue. The tongue should protrude in the midline when the client sticks it out. Cranial nerve IX (glossopharyngeal nerve) and X (vagus nerve) are tested by depressing the tongue with a blade to observe pharyngeal movement and gag reflex. Cranial nerve V (trigeminal nerve) is responsible for testing the muscles of mastication, not tongue protrusion.
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.
Which of the following is least appropriate when caring for a stable postpartum client?
- A. Assess the location and height of the fundus.
- B. Conduct a family assessment, including the mother's future plans for returning to work, if applicable.
- C. Monitor the client for bleeding.
- D. Provide perineal care.
Correct Answer: D
Rationale: Providing perineal care is not the least appropriate when caring for a stable postpartum client. Perineal care is essential for maintaining hygiene and preventing infection after delivery. Assessing the location and height of the fundus helps in monitoring postpartum uterine involution, which is crucial for assessing the recovery progress. Conducting a family assessment, including the mother's future plans for returning to work, is important for understanding the support system available for the mother during the postpartum period. Monitoring the client for bleeding is critical to promptly identify and address any postpartum hemorrhage. Therefore, providing perineal care is the least appropriate option among the choices provided as it is a fundamental aspect of postpartum care.
During a voice test, how should the nurse provide words for the client to repeat?
- A. Spoken in a soft tone of voice by the nurse about 5 feet in front of the client
- B. Whispered by the nurse from the client's side at a distance of 1 to 2 feet from the ear being tested
- C. Spoken by the nurse from the client's side in a normal tone of voice about 10 feet from the ear being tested
- D. Whispered at a distance of 20 feet by the nurse while he or she is standing in front of the client
Correct Answer: B
Rationale: During a voice test, the nurse should whisper words from the client's side at a distance of 1 to 2 feet from the ear being tested. This distance helps prevent transmission around the head and ensures accurate testing of one ear at a time. By standing close to the client and whispering, the nurse prevents lip-reading and compensatory actions by the client. The client with normal hearing should be able to repeat each word correctly. Choices A, C, and D are incorrect. Choice A is wrong as the voice should be whispered, not spoken in a soft tone. Choice C is inaccurate because a distance of 10 feet is too far for precise testing. Choice D is incorrect as whispering from a distance of 20 feet would not effectively test the client's hearing.
A healthcare professional is using an otoscope to inspect the ears of an adult client. Which action does the professional take before inserting the otoscope?
- A. Pulling the pinna up and back
- B. Pulling the pinna down and forward
- C. Tipping the client's head down and toward the examiner
- D. Tipping the client's head down and away from the examiner
Correct Answer: A
Rationale: In an adult client, the healthcare professional should pull the pinna up and back before inserting the otoscope. This action helps straighten the S shape of the ear canal, making it easier to insert the otoscope directly and comfortably. Tipping the client's head down and toward or away from the examiner is not the correct action when using an otoscope in an adult. Pulling the pinna down and forward is typically done when examining an infant or a child younger than 3 years old to straighten their ear canal for better visualization.
