Nursing Elites

1. A nurse calculates a newborn infant's Apgar score 1 minute after birth and determines that the score is 6. What is the most appropriate action for the nurse to take?

• A. Initiate cardiopulmonary resuscitation
• B. Gently stimulate the infant by rubbing his back while administering oxygen
• C. Recheck the score in 5 minutes
• D. Provide no action except to support the infant's spontaneous efforts

Correct answer: B

Rationale: The Apgar score is a method for rapidly evaluating an infant's cardiorespiratory adaptation after birth. The nurse assigns scores in five areas: heart rate, respiratory effort, muscle tone, reflex response, and color, totaling the scores. A score of 8 to 10 requires no action other than supporting the infant's spontaneous efforts and observation. A score of 4 to 7 indicates the need to gently stimulate the infant by rubbing his back while administering oxygen. If the score is 1 to 3, the infant requires resuscitation. Therefore, in this scenario with an Apgar score of 6, the correct action is to gently stimulate the infant by rubbing his back while administering oxygen. Initiating cardiopulmonary resuscitation would be excessive at this point, and rechecking the score in 5 minutes may delay necessary interventions. Providing no action except to support the infant's spontaneous efforts is insufficient for a score of 6, indicating the need for stimulation and oxygen administration.

2. An amniocentesis is scheduled for a pregnant client in the third trimester. The nurse informs the client that the most common indication for amniocentesis during the third trimester is for which reason?

• A. Determination of whether alpha-fetoprotein (AFP) is present in the amniotic fluid
• B. Checking the amniotic fluid for intrauterine infection
• C. Determination of fetal lung maturity
• D. Checking the fetal cells for chromosomal abnormalities

Correct answer: C

Rationale: The most common indication for amniocentesis in the third trimester is the determination of fetal lung maturity. This assessment is essential to evaluate the fetus's readiness for extrauterine life. Checking for alpha-fetoprotein (AFP) in the amniotic fluid is more commonly associated with midtrimester amniocentesis to identify chromosomal abnormalities. Assessing for intrauterine infection is not a primary reason for amniocentesis in the third trimester. While checking fetal cells for chromosomal abnormalities is a common indication for midtrimester amniocentesis, it is not the most common indication in the third trimester.

3. 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.

4. When a nurse asks a client to repeat the word 'ninety-nine' while listening through the stethoscope and is able to hear the word clearly, which assessment finding is being documented?

• A. Normal egophony
• B. Abnormal vesicular breath sounds
• C. Abnormal bronchophony
• D. Normal whispered pectoriloquy

Correct answer: C

Rationale: The nurse is documenting an abnormal bronchophony assessment finding. Bronchophony is a technique where the nurse asks the client to repeat a specific word, such as 'ninety-nine,' while listening through the stethoscope. Normally, the voice transmission is soft, muffled, and indistinct. However, if there is a pathologic condition increasing lung density, the nurse will hear the word clearly, indicating an abnormality. Vesicular breath sounds are normal sounds heard over peripheral lung fields and are not related to vocal resonance assessment. Egophony involves the client phonating a long 'ee-ee-ee-ee' sound, not repeating a specific word. Whispered pectoriloquy involves whispering a phrase like 'one-two-three,' not repeating a specific word. In these cases, normal findings are 'eeeeee' for egophony and a muffled, almost inaudible sound for whispered pectoriloquy.

5. A nurse assisting with data collection is preparing to auscultate for bowel sounds. The nurse should use which technique?

• A. Begin in the right lower quadrant.
• B. Use the bell end of the stethoscope.
• C. Hold the stethoscope lightly against the skin.
• D. Listen for at least 5 minutes before deciding that bowel sounds are absent.

Correct answer: A

Rationale: To auscultate for bowel sounds, the nurse should use the diaphragm end piece of the stethoscope as bowel sounds are relatively high pitched. The stethoscope should be held lightly against the skin to avoid stimulating more bowel sounds. The nurse should begin in the right lower quadrant at the ileocecal valve, where bowel sounds are normally present. It is recommended to listen for 5 minutes before deciding that bowel sounds are absent to ensure a thorough assessment. Choice B is incorrect because the bell end is used for low-pitched sounds such as heart sounds. Choice C is incorrect as holding the stethoscope firmly and deeply can cause unnecessary bowel sound stimulation. Choice D is incorrect as listening for 1 minute is insufficient to determine the presence or absence of bowel sounds.
