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?

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.

Correct Answer: D

Rationale: The best technique to determine a client's respiratory rate is to count respirations while pretending to check the client's pulse. You should not inform the client that you are counting their respirations, as this might lead to a change in their breathing pattern. Pretending to check the pulse allows you to be close to the client without revealing that you are assessing their respiratory rate. Asking the client to sit still may not be as effective, as it may cause them to concentrate on their breathing. Watching from across the room may not provide an accurate assessment of respirations, as they might be difficult to observe.

Correct Answer: D

Rationale: The correct answer is that the client mixes their medications with their tube-feeding formula. Medications should not be mixed with tube-feeding formula or other medications as it may alter their effectiveness. The G-tube should be flushed before, between, and after the medications to prevent clogging and ensure proper administration. The client should remain in the Semi-Fowler's position for at least 30 minutes after medication administration to prevent reflux. Choice B is correct as it aligns with the proper post-administration positioning. Choices A and C are incorrect as flushing the G-tube before, between, and after medications, and mixing each medication separately in warm water are appropriate procedures that do not indicate a need for further instruction.

Correct Answer: D

Rationale: The correct answer is 'Exposure to cigarette smoke.' Otitis media (middle ear infection) is associated with various factors like colds, allergies, sore throats, and blockage of the eustachian tubes. Risk factors include exposure to cigarette smoke, youth (as otitis media is usually a childhood disease), congenital abnormalities, immune deficiencies, family history of otitis media, recent upper respiratory infections, and allergies. Choices A, B, and C (Loud music, Use of power tools, and Occupational noise) are more likely to cause hearing loss rather than being direct risk factors for middle ear infections.

Correct Answer: D

Rationale: Muscle strength is graded on a scale of 0 to 5. A grade of 5 indicates normal strength and is described as full ROM against gravity with full resistance. Grade 4 indicates good strength and full ROM against gravity with some resistance. Grade 3 indicates fair strength and full ROM with gravity. Grade 2 indicates poor strength and full ROM with gravity eliminated (passive motion). Grade 1 indicates trace strength and slight contraction. Grade 0 indicates zero strength and no contraction. Therefore, the correct answer is 'Full ROM against gravity with some resistance.' Choices A, B, and C are incorrect as they do not match the description of muscle strength associated with a grade of 4.

Correct Answer: A

Rationale: The correct answer is the left lateral position. Placing the laboring client in the left lateral position is beneficial because it promotes blood flow to the placenta. Late decelerations indicate potential issues with fetal oxygenation, and changing the position to left lateral can help improve placental perfusion. Choices B, C, and D are incorrect because lithotomy, semi-Fowler's, and right lateral positions do not specifically address the need for improved blood flow to the placenta in cases of late decelerations.

Correct Answer: D

Rationale: The nurse should follow up on the client's lack of a support system. Even if there is no family in the area, there are supportive resources in the community that may help the client through the pregnancy and into motherhood. It is normal for the client to worry about labor, address financial concerns, and express displeasure from early pregnancy symptoms such as nausea. However, the priority is to address the client's statement about preparing to handle the pregnancy on her own due to the absence of nearby family support. This could have significant implications for the client's emotional well-being and ability to cope effectively throughout the pregnancy journey.

Correct Answer: A

Rationale: The penile skin typically appears wrinkled and hairless, without lesions, during a normal examination. Also, the scrotal skin naturally has a wrinkled appearance known as rugae. It is common for the left half of the scrotum to be positioned lower than the right, indicating normal asymmetry. Given these normal variations, the nurse should document the finding of wrinkled skin on the penis and scrotum. Checking for penile discharge or palpating for a mass in the scrotum is not indicated based on the presence of wrinkled skin, as this is a normal finding. Obtaining additional subjective data focusing on a scrotal abnormality is unnecessary since the wrinkled appearance is typical.

Correct Answer: B

Rationale: The correct answer is B. Amiodarone can cause increased photosensitivity, making it essential for the client to wear sunblock when exposed to sunlight. Choice A is incorrect because numbing or tingling in the feet is not a common side effect of Amiodarone. Choice C is unrelated as the drug does not typically require supplemental vitamin B12. Choice D is also incorrect as there is no need to avoid leafy vegetables specifically due to Amiodarone.
