Nursing Elites

1. A nurse in the telemetry unit is receiving the laboratory findings for an adult male client who is being treated for a myocardial infarction. Which of the following is an expected finding for the client?

• A. Troponin I (TnI) 8 ng/mL
• B. Brain natriuretic peptide (BNP) 10 ng/L
• C. Alanine aminotransferase (ALT) 45 units/L
• D. High-density lipoprotein (HDL) 75 mg/dL

Correct answer: A

Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.

2. A client tells the nurse that she suspects she is pregnant because she is able to feel the baby move. The nurse knows that this is a:

• A. Presumptive sign of pregnancy
• B. Probable sign of pregnancy
• C. Positive sign of pregnancy
• D. Possible sign of pregnancy

Correct answer: A

Rationale: The correct answer is A: Presumptive sign of pregnancy. Quickening, or the sensation of fetal movement, is considered a presumptive sign of pregnancy. It is not definitive because other conditions, such as gas or intestinal movement, can mimic the feeling of fetal movement. Choice B, Probable sign of pregnancy, refers to signs that make the nurse reasonably certain that a woman is pregnant, such as a positive pregnancy test. Choice C, Positive sign of pregnancy, includes signs like hearing fetal heart tones or visualizing the fetus on ultrasound, which definitively confirm pregnancy. Choice D, Possible sign of pregnancy, is a vague term and does not specifically relate to any pregnancy sign.

3. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: A PaCO2 level of 55 mm Hg indicates hypercapnia, which is common in clients with emphysema but may require further treatment if it leads to respiratory acidosis or distress. Elevated PaCO2 levels can indicate inadequate ventilation and impaired gas exchange, potentially leading to respiratory acidosis. The other results fall within normal ranges or compensated values for a client with chronic emphysema and do not necessarily indicate the need for immediate intervention.

4. A nurse is preparing to administer medications to a client who is NPO and has an NG tube for suction. Which of the following actions should the nurse take?

• A. Mix medications with enteral feedings.
• B. Clamp the NG tube for 30 minutes after medication administration.
• C. Insert medications directly into the NG tube without dilution.
• D. Connect the NG tube to continuous suction after medication.

Correct answer: B

Rationale: The correct action for the nurse to take when administering medications to a client with an NG tube for suction who is NPO is to clamp the NG tube for 30 minutes after medication administration. This is done to allow for proper absorption of the medications before resuming suction. Choice A is incorrect because medications should not be mixed with enteral feedings as it may affect the drug's effectiveness. Choice C is incorrect as medications should not be inserted directly into the NG tube without dilution, as this can cause clogging or affect the tube. Choice D is incorrect because connecting the NG tube to continuous suction after medication administration can interfere with the absorption of the medications.

5. A nurse is caring for a newborn who is 1 hour old and has a respiratory rate of 50 breaths per minute with periods of apnea lasting up to 10 seconds. Which of the following actions should the nurse take?

• A. Administer oxygen
• B. Stimulate the newborn
• C. Initiate positive pressure ventilation
• D. Continue routine monitoring

Correct answer: D

Rationale: A respiratory rate of 50 breaths per minute with occasional periods of apnea lasting less than 15 seconds is normal for a newborn. The nurse should continue routine monitoring unless the apneic periods become prolonged or the newborn shows signs of respiratory distress. Administering oxygen or initiating positive pressure ventilation is not indicated in this scenario as the newborn's respiratory rate and apneic episodes are within normal limits for their age. Stimulating the newborn is also unnecessary since the described parameters fall within the expected range for a 1-hour-old infant.
