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.

While assisting with data collection, the client informs the nurse that he is having difficulty swallowing medications and food. The nurse gathers additional subjective data and documents that the client is experiencing which disorder?
- A. Pyrosis
- B. Anorexia
- C. Eructation
- D. Dysphagia
Correct Answer: D
Rationale: The correct answer is 'Dysphagia.' Dysphagia is the term used to indicate difficulty swallowing, which can occur in disorders of the throat or esophagus. Anorexia refers to a loss of appetite, not difficulty swallowing. Eructation is the medical term for belching, not difficulty swallowing. Pyrosis is heartburn, a burning sensation in the esophagus and stomach caused by the reflux of gastric acid, not difficulty swallowing.
Which of the following are included in the Rights of Medication Administration? Select all that apply.
- A. Right dose, right time, right explanation, right client, right route
- B. Right dose, right time, right client, right route
- C. Right dose, right time, right client
- D. Right time, right explanation, right client
Correct Answer: B
Rationale: The Rights of Medication Administration include the right client, right drug, right dose, right route, and right time. An additional right that is sometimes included is the right documentation. The correct answer includes the essential rights that must be ensured during medication administration. Choice A is incorrect as 'right explanation' is not part of the traditional Rights of Medication Administration. Choice B is incorrect as 'right explanation' is not included, and choice C is missing the right route. Choice D is incorrect as it lacks the right dose and right route.
Around what age do children typically start to develop 'stranger anxiety'?
- A. 9 months
- B. 6 months
- C. 3 months
- D. 12 months
Correct Answer: B
Rationale: The correct answer is '6 months.' At around this age, children typically start to develop 'stranger anxiety' as they become more aware of unfamiliar faces and may start showing signs of distress or anxiety around strangers. At 3 months, infants are still very young and unlikely to display stranger anxiety. While by 9 or 12 months, children have usually already developed some level of stranger anxiety, it typically starts around 6 months, making it the most appropriate answer in this context.
A nurse is preparing to measure a client's calf circumference. The nurse performs this procedure by performing which action?
- A. Placing a tape measure around the widest point of the lower leg
- B. Measuring 2 inches above the knee and placing the tape measure around the client's leg at this point
- C. Measuring 2 inches above the ankle and placing the tape measure around the client's leg at this point
- D. Measuring 2 inches below the patella and placing the tape measure around the client's leg at this point
Correct Answer: A
Rationale: To measure a client's calf circumference accurately, a nurse should place a non-stretchable tape measure around the widest point of the lower leg. It is crucial to ensure that the tape measure is positioned at the same number of centimeters down from a specific landmark, such as the patella, on both legs for consistency. Placing the tape measure 2 inches above the knee (Option B), 2 inches above the ankle (Option C), or 2 inches below the patella (Option D) would not provide an accurate measurement of the calf circumference. Therefore, these options are incorrect choices.
The LPN is taking care of a client who is on Phenelzine (Nardil) for depression. Which meal would the nurse encourage the client to avoid?
- A. steak and potatoes
- B. prosciutto and cheese plate
- C. orange juice and toast
- D. carbonated water, shrimp and rice
Correct Answer: B
Rationale: The correct answer is 'prosciutto and cheese plate.' Phenelzine (Nardil) is an MAOI (Monoamine Oxidase Inhibitor), and clients on these drugs should avoid foods high in tyramine due to the risk of dangerous elevations in blood pressure. Prosciutto and aged cheeses are examples of foods rich in tyramine, so they should be avoided. Choices A, C, and D do not contain high levels of tyramine and are considered safe to consume while on Phenelzine.
