RN exams fundamentals practice questions set 33

Correct answer:

The correct answer is B: Using a cuff that covers two-thirds of the patient's upper arm. This is essential for obtaining an accurate blood pressure reading because using a cuff that is too small can result in falsely elevated readings, while using a cuff that is too large can result in falsely low readings. By covering two-thirds of the upper arm, the cuff ensures proper compression of the brachial artery, allowing for an accurate measurement. A: Positioning the patient's arm above the level of the heart is not essential for obtaining an accurate reading and can lead to inaccurate results. C: Deflating the cuff at a rate of 5-10 mm Hg per second is important but not as crucial as using the correct cuff size. D: Having the patient stand during the measurement is not recommended as blood pressure should be measured with the patient in a seated or lying position for accuracy.

Correct answer:

The correct answer is B: A bifid uvula may occur in some Native-American groups. A bifid uvula refers to a split or forked uvula, which is a variation of normal anatomy and can be seen in certain populations, including some Native-American groups. This condition is usually benign and does not typically cause any health issues. It is important for healthcare providers to be aware of such variations to avoid unnecessary concern or intervention. Explanation for incorrect options: A: This condition is not a cleft palate, which is a more severe congenital condition involving a gap in the roof of the mouth. C: There is no indication that the bifid uvula is due to an injury or that it should be reported to authorities. D: "Palatinus" is not a term commonly used to describe a bifid uvula, and the statement about its frequency in Native Americans is not supported by evidence.

Correct answer:

The correct answer is A: Use of accessory muscles during respiration. This finding in a patient with asthma indicates a need for immediate intervention because it signifies severe respiratory distress and impending respiratory failure. Accessory muscle use suggests that the patient is struggling to breathe and is unable to maintain adequate oxygenation. This requires prompt medical attention to prevent further deterioration. Summary: B: Oxygen saturation of 92% on room air may indicate mild hypoxemia but is not as urgent as the use of accessory muscles. C: Mild expiratory wheezing is a common finding in asthma exacerbations and may not necessarily require immediate intervention. D: Peak expiratory flow rate of 85% of personal best indicates moderate airflow limitation but does not necessarily require immediate intervention unless accompanied by other severe symptoms.

Correct answer:

The correct answer is B: Assess the patient's ability to chew and detect light touch on the face. This is the most appropriate action for assessing cranial nerve V (trigeminal nerve) as this nerve is responsible for sensory functions of the face and motor function of the muscles of mastication. By assessing the patient's ability to chew and detecting light touch on the face, the nurse can evaluate the integrity of the trigeminal nerve. Choice A is incorrect because assessing the patient's ability to shrug their shoulders against resistance would be more indicative of assessing cranial nerve XI (accessory nerve). Choice C is incorrect because checking for gag reflex and swallowing is more related to cranial nerves IX (glossopharyngeal) and X (vagus). Choice D is incorrect because evaluating the patient's hearing ability is related to cranial nerve VIII (vestibulocochlear).

Correct answer:

The correct answer is A: Encouraging fluid intake of at least 3 liters per day. Increasing fluid intake helps to thin the mucus, making it easier to clear from the airways. Adequate hydration also helps to keep the mucus membranes moist, facilitating mucus clearance. This intervention promotes effective coughing and expectoration, ultimately aiding in clearing the excess mucus associated with bronchitis. Choice B: Administering prescribed antitussive medication would not be effective in promoting mucus clearance as antitussives suppress coughing, which is needed to clear mucus. Choice C: Positioning the client in a high Fowler's position may improve breathing but does not directly address mucus clearance. Choice D: Limiting activity to conserve energy does not promote mucus clearance. In fact, some degree of activity can help mobilize mucus and facilitate its clearance.

Correct answer:

A blood pressure reading of 120/80 mm Hg is considered normal according to widely accepted medical guidelines, such as those from the American Heart Association. The systolic pressure (120 mm Hg) represents the force when the heart contracts, and the diastolic pressure (80 mm Hg) reflects the pressure when the heart is at rest. Normal blood pressure is typically defined as systolic less than 120 mm Hg and diastolic less than 80 mm Hg, making Normal, correct. Prehypertension, applies to readings like 120-129/<80 mm Hg, but 120/80 exceeds this slightly yet remains within normal limits in many contexts. Hypotensive, indicates low blood pressure (e.g., below 90/60 mm Hg), which 120/80 clearly is not. Hypertensive, refers to high blood pressure (e.g., 130/80 mm Hg or higher), which this reading does not meet. Therefore, C is the accurate answer based on standard classifications.

Correct answer:

The correct answer is D: Prevent pulmonary complications. Using an incentive spirometer post-thoracic surgery helps prevent atelectasis and pneumonia by promoting lung expansion, improving ventilation, and clearing secretions. This intervention aids in maintaining lung function and preventing respiratory complications. A: Promote relaxation - While using an incentive spirometer may induce relaxation as a side effect, the primary purpose is not relaxation but rather to prevent pulmonary complications. B: Improve inspiratory muscle strength - Although using an incentive spirometer can help improve inspiratory muscle strength, the primary purpose is to prevent pulmonary complications. C: Reduce pain during breathing - While using an incentive spirometer may indirectly reduce pain by promoting optimal lung function, the primary purpose is to prevent pulmonary complications.

The systolic pressure (120 mm Hg) represents the force when the heart contracts, and the diastolic pressure (80 mm Hg) reflects the pressure when the heart is at rest. Normal blood pressure is typically defined as systolic less than 120 mm Hg and diastolic less than 80 mm Hg, making Normal, correct. Prehypertension, applies to readings like 120-129/<80 mm Hg, but 120/80 exceeds this slightly yet remains within normal limits in many contexts. Hypotensive, indicates low blood pressure (e.g., below 90/60 mm Hg), which 120/80 clearly is not. Hypertensive, refers to high blood pressure (e.g., 130/80 mm Hg or higher), which this reading does not meet. Therefore, C is the accurate answer based on standard classifications.

Correct answer:

The correct answer is D. When a woman slowly lifts her arms above her head during a breast examination, it allows for better visualization and detection of any nipple or skin retraction. This position stretches the breast tissue and skin, making any abnormalities more apparent. Additionally, observing for any lag or retraction in movement while the arms are raised can help identify any potential issues. Choice A is incorrect because bending over and touching her toes does not provide the necessary positioning to properly assess for nipple and skin retraction. Choice B is incorrect because lying down on the left side may not provide the same level of stretching and visibility as lifting the arms above the head. Choice C is incorrect because shifting from a supine position to a standing position may not provide the optimal angle for assessing nipple and skin retraction.

Correct answer:

The correct answer is B: The chest drainage must be observed for amount and color. This statement is true because monitoring the amount and color of chest drainage is crucial in assessing the resident's condition, detecting any signs of bleeding or infection. It helps in determining the effectiveness of the chest tube in removing air or fluid from the pleural space. Incorrect choices: A: The drainage system must be kept above the level of the resident's chest - This is incorrect as the drainage system should be kept below the level of the resident's chest to facilitate drainage. C: The tubing should be kinked - Kinking the tubing can obstruct the flow of drainage, which is harmful. D: Chest tubes will only be in the front of the body - Chest tubes can be placed in various locations depending on the specific condition being treated, not just in the front of the body.
