NR 509 APEA 3P Exam Week 8 Grade A Plus Latest Verified Review 2023 Practice Questions and Answers for Exam Preparation, 100% Correct with Explanations, Highly Recommended, Download to Score A+ Question 1 A 3 year-old presents with a history of fever and cough over the past 24 hours. Findings on exam reveal: temperature of 102°F, apical heart rate of 157 beats/minute, and respiratory rate of 40 breaths/minute. Tachypnea in this child is most likely related to Correct: the child's febrile state. Explanation: In children, heart and respiratory rates will increase with fever. For every degree of fever the respiratory rate will increase 3-4 breaths/minutes and the heart rate will increase 8-10 beats/minute. Question 2 When percussing the lower posterior chest, begin by: Correct: having the patient lie supine on the examining table. Explanation: When percussing the lower posterior chest, stand on the side rather than directly behind the patient. This position allows the ability to place the pleximeter finger more firmly on the chest and the plexor is more effective in making a better percussion note. If the patient is lying supine, the posterior chest will not be able to be percussed. Palpating painful areas is not percussion, so is not correct. Using the bony part of the palm at the base of the fingers or the ulnar surface is a technique used to detect tactile fremitus. Question 3 The palpation technique used to assess respiratory expansion of the chest is placing the hands on the eight or tenth ribs posteriorly with the thumbs close to the vertebrae, sliding the hand medially and grasping a small fold of skin between the thumbs. Then: Correct: have the patient hold his breath for 15 seconds then note chest expansion. Explanation: To assess the respiratory expansion of the chest, the examiner places his hands on the eight or tenth ribs posteriorly with the thumbs close to the vertebrae, slides the hand medially and grasps a small fold of skin between the thumbs then asks the patient to take a deep breath. The thumbs should move evenly away from the vertebrae during inspiration and there should be no delay in expansion. Question 4 When trying to differentiate between hemoptysis or blood streaked material, which one of the following observations is correct? Correct: Blood streaked material often originates from the gastrointestinal tract. Explanation: Hemoptysis is rare in infants, children, and adolescents, although common in those with cystic fibrosis. Blood originating in the stomach is usually darker than blood from the respiratory tract and may be mixed with food particles. Blood or blood-streaked material may originate in the mouth, pharynx, or less commonly from the gastrointestinal tract. Question 5 When percussing the chest in a patient who has left sided heart failure, the sound emanated would be: Correct: resonant. Explanation: A patient with left sided heart failure experiences increased pressure in the pulmonary veins causing congestion and interstitial edema. Percussion sounds emitted would most likely be resonant. Consolidation in the lungs produces a dull sound on percussion. Tympany (low-high pitched musical sound) is usually audible when percussing a distended abdomen or when a pneumothorax is present. Chronic obstructive lung disease produces diffusely hyperresonant sound on percussion.
