Nursing Elites

1. The mitral valve is synonymous with the term:

• A. Left ventricle
• B. Right atrium
• C. Bicuspid valve
• D. Tricuspid valve

Correct answer: C

Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (Choice D), which has three cusps, making Choice D incorrect. The left ventricle (Choice A) and right atrium (Choice B) are not synonymous with the mitral valve. Therefore, the correct answer is C: Bicuspid valve.

2. A nurse is preparing to insert a small-bore nasogastric feeding tube for a client's enteral feedings. In which method does the nurse measure the correct length of the tube?

• A. From the tip of the nose to the xiphoid process
• B. From the tip of the nose to the earlobe to the xiphoid process
• C. From the earlobe to the xiphoid process
• D. From the tip of the nose to the earlobe to the umbilicus

Correct answer: B

Rationale: When preparing to insert a nasogastric tube, the nurse must measure the correct length to ensure that the end of the tube will be in the correct position in the stomach. The accurate method to measure the length is from the tip of the nose to the earlobe to the xiphoid process. This length ensures that the end of the tube reaches the stomach, avoiding placement in the small intestine or esophagus. Choice A is incorrect as it does not include the earlobe, which is essential for accurate measurement. Choice C is incorrect because measuring from the earlobe alone does not provide the correct length for positioning in the stomach. Choice D is incorrect as it includes the umbilicus, which is not the appropriate landmark for measuring the length of a nasogastric tube intended for stomach placement.

3. A client is being seen for disrupted sleep patterns. The nurse encourages the client to verbalize feelings about sleep and inability to maintain adequate sleep habits. What is the rationale for this action?

• A. The client most likely has a mental illness that should be treated before addressing sleep issues
• B. The client may have unrecognized anxiety or fear that could be contributing to poor sleep habits
• C. The client may become tired once they start talking
• D. None of the above

Correct answer: B

Rationale: Clients experiencing disrupted sleep patterns may have underlying anxiety or fear contributing to their poor sleep habits. Encouraging clients to verbalize their feelings about sleep allows them to address any negative emotions that may be impacting their ability to sleep well. By working through these issues, clients may experience increased peace and relaxation, which can help promote better sleep. Option A is incorrect because assuming a mental illness without evidence can lead to mismanagement of the client's care. Option C is incorrect as it does not address the underlying emotional factors affecting the client's sleep patterns. Option D is incorrect as there is a specific rationale for encouraging the client to verbalize their feelings about sleep.

4. A 4-month-old child is at the clinic for a well-baby checkup and immunizations. Which of these actions is most appropriate when the nurse is assessing an infant's vital signs?

• A. The infant's radial pulse should be palpated, and the nurse should notice any fluctuations resulting from activity or exercise.
• B. The nurse should auscultate an apical rate for 1 minute and then assess for any normal irregularities, such as sinus dysrhythmia.
• C. The infant's blood pressure should be assessed by using a stethoscope with a large diaphragm piece to hear the soft muffled Korotkoff sounds.
• D. The infant's chest should be observed and the respiratory rate counted for 1 minute; the respiratory pattern may vary significantly.

Correct answer: B

Rationale: The nurse auscultates an apical rate, not a radial pulse, with infants and toddlers. The pulse should be counted by listening to the heart for 1 full minute to account for normal irregularities, such as sinus dysrhythmia. Children younger than 3 years of age have such small arm vessels; consequently, hearing Korotkoff sounds with a stethoscope is difficult. The nurse should use either an electronic blood pressure device that uses oscillometry or a Doppler ultrasound device to amplify the sounds. An infant's respiratory rate should be assessed by observing the infant's abdomen, not chest, because an infant's respirations are normally more diaphragmatic than thoracic. The nurse should auscultate an apical heart rate, not palpate a radial pulse, with infants and toddlers.

5. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?

• A. Yield a falsely low blood pressure
• B. Yield a falsely high blood pressure
• C. Be the same, regardless of cuff size
• D. Vary as a result of the technique of the person performing the assessment

Correct answer: B

Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
