a urine pregnancy test

NCLEX-RN

NCLEX RN Predictor Exam

1. A urine pregnancy test:

A. May be negative even if a blood pregnancy test is positive.
B. Is positive only during the first trimester of pregnancy.
C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
D. All of the above.

Correct answer: A

Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.

2. A nurse is completing an incident report about a medication error that she made when she accidentally administered too much insulin to a diabetic client. All of the following are components of this documentation EXCEPT:

A. The reason for administering the wrong dose
B. The type of drug involved
C. The amount of insulin that was given
D. Any adverse effects on the client

Correct answer: A

Rationale: When completing an incident report for a medication error, it is essential to include factual information such as the type of drug involved, the amount administered, and any adverse effects on the client. However, stating the reason for administering the wrong dose should be avoided in documentation. The focus should be on reporting what happened rather than assigning blame or admitting fault. This approach helps in ensuring a thorough and accurate account of the medication error without introducing subjective elements that could complicate the investigation or resolution process. Therefore, the correct answer is 'The reason for administering the wrong dose.' Choices A, B, and D are vital components of incident report documentation, providing crucial details that help in understanding the error and its impact on the client.

3. Which of the following is a disadvantage of using a dry heat application?

A. Dry heat is more likely to cause burns than moist heat
B. Dry heat does not penetrate deeply into the tissues
C. Dry heat causes the skin to dry out more quickly
D. Dry heat can quickly cause skin breakdown

Correct answer: C

Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.

4. A client is complaining of pain in his right hand after surgery. The IV in his hand has slowed down, and the skin around the site is reddened and cool. The client reports localized pain in the hand and fingers. What is the most likely cause of this client's pain?

A. The client's IV is infiltrated
B. The client is experiencing phlebitis from the last drug administered
C. The client has a blood clot developing in the distal arteries of the wrist
D. The client's pain is associated with myocardial ischemia and he is having a heart attack

Correct answer: A

Rationale: Pain, cool skin, and edema at an IV injection site indicate IV infiltration. The reddened and cool skin around the IV site, along with localized pain and a slowed IV drip rate, are classic signs of infiltration. Infiltration occurs when IV fluids or medications enter the surrounding tissues instead of the vein, leading to potential tissue damage. Phlebitis is inflammation of a vein, not infiltration. A blood clot in the distal arteries of the wrist would not cause these specific symptoms. Myocardial ischemia and heart attack are unrelated to the client's localized hand pain and IV issues.

5. The nurse is assessing the vital signs of a 20-year-old marathon runner and documents the following vital signs: temperature"?36�C; pulse"?48 beats per minute; respirations"?14 breaths per minute; blood pressure"?104/68 mm Hg. Which statement is true concerning these results?

A. The patient is experiencing bradycardia.
B. These are normal vital signs for a healthy, athletic adult.
C. The patient's pulse rate is not normal"?no action is required.
D. The patient's next clinic visit should occur as scheduled.

Correct answer: B

Rationale: The correct answer is, 'These are normal vital signs for a healthy, athletic adult.' A pulse rate of 48 beats per minute is considered bradycardia in adults, but it is not a concern in well-trained athletes like marathon runners. Bradycardia is a normal physiological response to aerobic conditioning. Tachycardia, on the other hand, is defined as a pulse rate above 100 beats per minute, which is not the case here. The low pulse rate in this scenario is a reflection of the athlete's cardiovascular fitness. Therefore, there is no need to notify the physician or schedule a follow-up visit based on these findings.
