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. During a general survey of a patient, which finding is considered normal?

• A. Body mass index (BMI) of 20.
• B. When standing, the patient's base is narrow.
• C. The patient appears older than their stated age.
• D. Arm span (fingertip to fingertip) is greater than the height.

Correct answer: A

Rationale: A body mass index (BMI) of 20 is considered normal as the range for a normal BMI is between 19-24. When standing, a patient's base should be wide for stability and proper weight distribution. An older appearance than the stated age may indicate a history of chronic illness or chronic alcoholism. In a general survey, the patient's arm span (fingertip to fingertip) should approximately equal the patient's height. An arm span greater than the height may suggest Marfan syndrome. Therefore, the correct choice is a normal BMI of 20, which falls within the healthy range. Choices B, C, and D all describe abnormal findings that may indicate underlying health conditions or syndromes.

3. A client with an enlarged prostate is having trouble starting his flow of urine when using the bathroom. Another name for this condition is:

• A. Hesitancy
• B. Oliguria
• C. Retention
• D. Urgency

Correct answer: A

Rationale: Urinary hesitancy occurs when a client has difficulty starting a flow of urine while using the bathroom. Hesitancy may be due to physiological factors, such as obstruction from an enlarged prostate, or due to psychological factors, such as anxiety or embarrassment. Oliguria refers to decreased urine output, retention is the inability to empty the bladder fully, and urgency is the sudden and strong need to urinate.

4. When providing mouth care to a patient in a coma, what should you do to provide good and safe mouth care?

• A. keep the head of the bed up to prevent aspiration
• B. brush the teeth and rinse the mouth with a cup of water
• C. use a special foam swab to brush only the tongue
• D. use a special foam swab to brush the tongue and teeth

Correct answer: D

Rationale: When providing mouth care to a patient in a coma, it is crucial to use a special foam swab to brush the tongue and teeth. This method helps maintain good oral hygiene for comatose patients. Special foam swabs are designed to effectively clean all areas of the mouth, including the cheeks and tongue, ensuring thorough care. Using water for mouth care in comatose patients can lead to aspiration, so it is important to avoid this practice. Keeping the head of the bed up alone does not prevent aspiration during mouth care for comatose patients, making choice A incorrect. Merely brushing the tongue (choice C) or using a foam swab only on the tongue (choice B) may not provide the comprehensive mouth care necessary for patients in a coma.

5. When providing endotracheal suctioning, for how long should the nurse suction the endotracheal tube of an intubated client on a ventilator at a time?

• A. Five seconds or less
• B. Ten seconds or less
• C. At least 30 seconds
• D. No longer than 60 seconds

Correct answer: B

Rationale: When providing endotracheal suctioning, the nurse should suction for no longer than ten seconds at a time. Suctioning for longer than ten seconds may cause hypoxia or bronchospasm. Extended suctioning may also place the client at risk of injury to the bronchial and tracheal structures. Choices C and D suggest prolonged suctioning durations that can lead to adverse effects on the client. Choice A, suctioning for five seconds or less, may not be adequate to clear secretions effectively, making choice B the most appropriate duration for safe and efficient suctioning in this scenario.
