Nursing Elites

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. The healthcare professional has collected the following information on a patient: palpated blood pressure"?180 mm Hg; auscultated blood pressure"?170/100 mm Hg; apical pulse"?60 beats per minute; radial pulse"?70 beats per minute. What is the patient's pulse pressure?

• A. 10
• B. 70
• C. 80
• D. 100

Correct answer: B

Rationale: Pulse pressure is the numerical difference between the systolic and diastolic blood pressure readings. In this case, the systolic blood pressure is 170 mm Hg, and the diastolic blood pressure is 100 mm Hg. Therefore, the pulse pressure is calculated as 170 - 100 = 70 mm Hg. Pulse pressure reflects the stroke volume, the amount of blood ejected from the heart with each beat. Choices A, C, and D are incorrect because they do not accurately represent the difference between the systolic and diastolic blood pressure readings provided.

3. A client is preparing to irrigate a colostomy. Which of the following situations is a contraindication for this type of irrigation?

• A. The client has an incontinent ostomy
• B. The client has an irregular bowel routine
• C. The client has diverticulitis
• D. The colostomy bag contains fecal material

Correct answer: C

Rationale: When a client with a colostomy is preparing for irrigation, it is essential to consider contraindications that could pose risks or worsen the client's condition. Diverticulitis is a contraindication for colostomy irrigation because the inflamed diverticula could be further irritated by the flushing action during irrigation, potentially leading to complications. An incontinent ostomy, irregular bowel routine, or presence of fecal material in the colostomy bag are not specific contraindications for irrigation and can be managed through appropriate techniques and interventions.

4. Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)

• A. HCV
• B. HPV
• C. HIV
• D. HBV

Correct answer: A

Rationale: The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.

5. A patient is seen in the clinic for reports of "fainting episodes that started last week."? How would the nurse proceed with the examination?

• A. Blood pressure readings are taken in both arms and thighs.
• B. The patient is assisted to a lying position, and their blood pressure is taken.
• C. The patient's blood pressure is recorded in lying, sitting, and standing positions.
• D. The patient's blood pressure is recorded in lying and sitting positions; these numbers are then averaged to obtain a mean blood pressure.

Correct answer: C

Rationale: When a patient reports fainting episodes, it is crucial to assess for orthostatic hypotension. If the nurse suspects volume depletion, the patient has hypertension, is on antihypertensive medications, or has a history of fainting or syncope, blood pressure readings should be taken in three positions: lying, sitting, and standing. This assessment helps detect orthostatic hypotension, which can provide valuable information about the patient's condition. Taking blood pressure readings in multiple positions allows for a comprehensive evaluation of possible postural changes in blood pressure. Choices A, B, and D are incorrect because they do not cover the necessary positions to assess for orthostatic hypotension effectively.
