During a cardiovascular assessment, the nurse palpates the left chest at the midclavicular line in the 5th intercostal space. What is the nurse assessing?
-
The jugular venous pulse
-
The pulmonic area
-
The aortic pulsation
-
The point of maximal impulse
Explanation
Correct Answer: (D) The point of maximal impulse
The point of maximal impulse (PMI) is normally located at the 5th intercostal space at the midclavicular line, corresponding to the apex of the heart. This is where the heartbeat is most strongly felt during palpation.
Why Other Options are Incorrect:
A. The jugular venous pulse This is assessed by observing the jugular veins in the neck, not by palpating the chest wall.
B. The pulmonic area This area is located at the 2nd intercostal space, left sternal border, not at the midclavicular line in the 5th intercostal space.
C. The aortic pulsation This is assessed at the 2nd intercostal space, right sternal border, not at the location described.
While assessing a client's gait, the nurse notes an uncoordinated, unsteady gait. How should the nurse document this gait?
-
Shuffling
-
Ataxia
-
Scissors
-
Tandem walking
Explanation
Correct Answer: (B) Ataxia
Ataxia refers to an uncoordinated, unsteady gait resulting from impaired muscle control, often due to a neurological issue affecting balance and coordination.
Why Other Options are Incorrect:
A. Shuffling This describes a gait with short, sliding steps and minimal foot lifting, often seen in Parkinson's disease, not uncoordinated unsteadiness.
C. Scissors This describes a gait in which the legs cross over each other with each step, often due to spasticity, not general uncoordination.
D. Tandem walking This refers to a heel-to-toe walking technique used to assess balance, not a description of an abnormal gait pattern itself.
-
Right ventricle
-
Aorta
-
Right atrium
-
Left atrium
Explanation
Correct Answer: (D) Left atrium
After blood is oxygenated in the lungs, it travels through the pulmonary veins and enters the left atrium, which then pumps the blood into the left ventricle before it is distributed to the rest of the body.
Why the other options are incorrect:
A. Right ventricle This chamber pumps deoxygenated blood to the lungs; it does not receive the newly oxygenated blood returning from the lungs.
B. Aorta This vessel carries oxygenated blood from the left ventricle to the body, but blood must pass through the left atrium and left ventricle before reaching it.
C. Right atrium This chamber receives deoxygenated blood from the body, not oxygenated blood from the lungs.
Answer: 1415
Explanation
500 mL divided by 80 mL/hr equals 6.25 hours, which is 6 hours and 15 minutes. Adding 6 hours and 15 minutes to the start time of 0800 gives a completion time of 1415.
The nurse is conducting a musculoskeletal assessment on a school-aged child to screen for scoliosis. Which instruction should the nurse give to properly assess for spinal curvature?
-
"Stand on one foot and then the other while I check your balance."
-
"Lie flat on your back while I measure the length of your legs."
-
"Bend forward at the waist with your arms hanging loosely while I observe your spine."
-
"Turn your head from side to side while keeping your shoulders still."
Explanation
This instruction describes the Adam's forward bend test, the standard screening technique used to assess for scoliosis. Bending forward with arms hanging loosely allows the nurse to visualize the spine and detect any asymmetry, such as a rib hump or curvature, that may indicate scoliosis.
Why the other options are incorrect:
A. "Stand on one foot and then the other while I check your balance." — This instruction assesses balance and lower extremity coordination, not spinal curvature.
B. "Lie flat on your back while I measure the length of your legs." — This instruction assesses for leg length discrepancy, which is a different musculoskeletal assessment unrelated to the standard scoliosis screening technique.
D. "Turn your head from side to side while keeping your shoulders still." — This instruction assesses cervical spine range of motion, not the thoracic/lumbar spinal curvature associated with scoliosis screening.
The nurse is caring for a client that was diagnosed with a bacterial infection. What structures of the body contain lymphatic tissue that assist in fighting infections? (Select all that apply)
-
Gallbladder
-
Bone marrow
-
Stomach
-
Spleen
-
Thymus
Explanation
Correct Answer: (B) Bone marrow, (D) Spleen, (E) Thymus
Bone marrow, spleen, and thymus are all lymphoid organs that play essential roles in the immune system. Bone marrow produces lymphocytes, the spleen filters blood and helps fight infection, and the thymus is where T-lymphocytes mature.
Why the other options are incorrect:
A. Gallbladder This organ stores and concentrates bile for digestion and does not contain lymphatic tissue involved in immune function.
C. Stomach This organ is part of the digestive system responsible for breaking down food and does not primarily contain lymphatic tissue for immune defense.
Answer:
Total intake amount: 1400 mL Total output amount: 990 mL
-
Total intake amount: 1400 mL Total output amount: 990 mL
Explanation
Correct Answer: Total intake = 1400 mL; Total output = 990 mL
Intake is calculated by converting all fluid volumes to milliliters: 100 mL water with medications, 8 oz tea (240 mL), 1 cup of chicken broth (240 mL), 1 cup of ice chips (counted at half volume, 120 mL), 500 mL Lactated Ringer's IV, and 200 mL Vancomycin IV, totaling 1,400 mL. Output includes all measured fluid losses: 300 mL urine, 90 mL emesis, 400 mL urine, and 200 mL urine, totaling 990 mL.
-
Generalized weakness
-
Positive toe tapping
-
Daily fatigue
-
Uncoordinated movements
Explanation
Correct Answer: (D) Uncoordinated movements
Uncoordinated movements can indicate a significant neurological deficit, such as cerebellar dysfunction, stroke, or another acute central nervous system issue, and require prompt further evaluation.
Why the other options are incorrect:
A. Generalized weakness While this can be concerning, it is often a vague, nonspecific finding compared to uncoordinated movements, which more directly indicates a neurological deficit affecting motor control.
B. Positive toe tapping This is a normal finding used to assess rapid alternating movements and coordination; a positive/normal result is not a cause for concern.
C. Daily fatigue This is a common, nonspecific symptom that can be related to many benign causes and is not as acutely concerning as uncoordinated movements.
The nurse is assessing a client's cranial nerve function by checking for pupil constriction in response to light and testing eye movement in multiple directions. Which cranial nerve is the nurse assessing?
-
Abducens nerve (Cranial Nerve VI)
-
Trigeminal nerve (Cranial Nerve V)
-
Oculomotor nerve (Cranial Nerve III)
-
Vagus nerve (Cranial Nerve X)
Explanation
The oculomotor nerve (CN III) controls pupillary constriction in response to light (via parasympathetic fibers) and innervates most of the extraocular muscles responsible for eye movement in multiple directions, making it the nerve being assessed through both of these described actions.
Why the other options are incorrect:
A. Abducens nerve (Cranial Nerve VI) — This nerve controls only lateral eye movement (abduction) via the lateral rectus muscle and has no role in pupillary constriction, making it too limited to account for both described findings.
B. Trigeminal nerve (Cranial Nerve V) — This nerve is responsible for facial sensation and mastication (chewing) muscles, playing no role in pupillary response or eye movement.
D. Vagus nerve (Cranial Nerve X) — This nerve is responsible for parasympathetic innervation of thoracic and abdominal organs, swallowing, and phonation, playing no role in pupillary response or eye movement.
The nurse is auscultating a client's heart sounds to assess for a possible aortic murmur. Which action should the nurse take to improve accuracy when listening for this unexpected sound?
-
Place the stethoscope at the second intercostal space, right sternal border. Ask the client to sit up and lean forward.
-
Assess the murmur only in a supine position while listening with the diaphragm of the stethoscope.
-
Position the client in the left lateral position and listen at the apex of the heart using the bell of the stethoscope.
-
Instruct the client to hold their breath and place the stethoscope at the third intercostal space, left sternal border.
Explanation
The aortic valve is best auscultated at the second intercostal space, right sternal border (the aortic area). Having the client sit up and lean forward brings the heart closer to the anterior chest wall, which enhances the ability to hear aortic murmurs, particularly those associated with aortic regurgitation, more clearly.
Why the other options are incorrect:
B. Assess the murmur only in a supine position while listening with the diaphragm of the stethoscope. — Relying solely on the supine position limits diagnostic accuracy, as certain positioning maneuvers (such as sitting up and leaning forward) are specifically used to enhance detection of aortic murmurs.
C. Position the client in the left lateral position and listen at the apex of the heart using the bell of the stethoscope. — The left lateral position and apex auscultation with the bell are techniques used to assess mitral valve sounds (such as S3, S4, or mitral stenosis), not the aortic area.
D. Instruct the client to hold their breath and place the stethoscope at the third intercostal space, left sternal border. — This location (Erb's point) is not the primary auscultation site for the aortic valve, and breath-holding is not the specific positioning technique recommended to enhance aortic murmur detection.
