The nurse documents tonsils as "3+." What does this mean?
- Tonsils are halfway to the uvula
- Tonsils are barely visible
- Tonsils are touching each other
- Tonsils are touching the uvula
Explanation
Explanation:
Correct Answer: (A) Tonsils are halfway to the uvula
Tonsil grading uses a standardized scale from 0 to 4+. A grade of 3+ means the tonsils have extended past the anterior pillars and are halfway between the pillars and the uvula. This indicates significant enlargement that warrants clinical attention but has not yet reached the most severe grade.
Why Other Options are Incorrect:
B. Tonsils are barely visible — This describes a 1+ grading, where the tonsils are within the tonsillar pillars and minimally visible.
C. Tonsils are touching each other — This corresponds to a 4+ grading, also referred to as "kissing tonsils," representing the most severe degree of enlargement.
D. Tonsils are touching the uvula — This is not a standard descriptor in the tonsil grading scale and does not correspond to any recognized grading level.
The kindergarten student tells the school nurse that she can't hear out of her left ear. The nurse inspects the ear canal and sees a bright green object. Which condition does the nurse suspect? Select all that apply.
- Cerumen impaction
- Presbycusis
- Sensorineural hearing loss
- Conductive hearing loss
- Foreign body obstruction
Explanation
Explanation:
Correct Answers: (D) Conductive hearing loss and (E) Foreign body obstruction
A bright green object visible in the ear canal of a kindergarten-aged child is highly indicative of a foreign body obstruction, as young children frequently insert objects into their ears. This physical blockage of the ear canal prevents sound waves from reaching the middle and inner ear, resulting in conductive hearing loss, which is hearing loss caused by a mechanical obstruction rather than nerve damage.
Why Other Options are Incorrect:
A. Cerumen impaction — While cerumen can cause conductive hearing loss, the nurse visualized a bright green object, not earwax, making this an incorrect primary suspicion.
B. Presbycusis — This is age-related hearing loss that occurs in older adults and is entirely irrelevant in a kindergarten-aged child.
C. Sensorineural hearing loss — This type of hearing loss results from damage to the inner ear or auditory nerve and would not be caused by a visible foreign object in the canal.
When examining the eye, where will the nurse most likely find signs of liver disease?
- Macula
- Cornea
- Sclera
- Limbus
Explanation
Explanation:
Correct Answer: (C) Sclera
The sclera, commonly known as the white of the eye, is the most visible location where jaundice associated with liver disease can be detected. When the liver is unable to properly process bilirubin, it accumulates in the body and causes a yellowing of the skin and mucous membranes, most noticeably in the sclera. This finding is referred to as scleral icterus and is one of the earliest and most reliable clinical signs of liver disease or biliary obstruction.
Why Other Options are Incorrect:
A. Macula — The macula is a small area at the center of the retina responsible for sharp central vision. It is an internal structure not directly visible without specialized equipment and is not associated with signs of liver disease.
B. Cornea — The cornea is the clear outer covering of the eye. While it can show findings in certain metabolic conditions such as Wilson's disease (Kayser-Fleischer rings), it is not the primary location where jaundice from liver disease is observed.
D. Limbus — The limbus is the border between the cornea and the sclera and is not the area where signs of liver disease such as jaundice are typically identified during routine eye examination.
The nurse notes redness and tenderness at the patient's IV insertion site. What should the nurse do next?
- Apply a warm compress to the IV site.
- Flush the IV line with normal saline to check patency.
- Remove the IV and restart it in another location.
- Document the finding and continue to monitor.
Explanation
Explanation:
Correct Answer: (C) Remove the IV and restart it in another location.
Redness and tenderness at an IV insertion site are classic signs of phlebitis or early infiltration, indicating that the IV site is compromised. The priority action is to discontinue the IV immediately and restart it in a new location to prevent further inflammation, tissue damage, or risk of infection. Leaving a compromised IV in place poses significant risk to the patient.
Why Other Options are Incorrect:
A. Applying a warm compress may provide comfort after the IV is removed but is not the priority action; the compromised IV must first be discontinued before any comfort measures are applied.
B. Flushing a compromised IV line with normal saline when signs of phlebitis or infiltration are present can worsen tissue damage and is contraindicated; flushing does not resolve the underlying problem.
D. Simply documenting and continuing to monitor a site showing active signs of phlebitis delays necessary action and allows the condition to worsen, potentially leading to infection, thrombophlebitis, or tissue necrosis.
The nurse is teaching a group of women about health-promoting interventions. Which health interventions are most responsible for the decline in cervical cancer rates? Select all that apply.
- Oral contraceptives.
- Female circumcision.
- Vitamin supplementation.
- Vaccination against human papillomavirus (HPV). E. Pap test screening.
Explanation
Explanation:
Correct Answers: (D) Vaccination against human papillomavirus (HPV) and (E) Pap test screening.
The two interventions most responsible for the dramatic decline in cervical cancer rates are HPV vaccination and regular Pap test screening. HPV vaccination prevents infection with the high-risk strains of HPV (types 16 and 18) responsible for approximately 70% of cervical cancers. Pap test screening enables early detection of precancerous cervical changes (dysplasia) before they progress to invasive cancer, allowing for timely treatment and prevention of cancer development.
Why Other Options are Incorrect:
A. Oral contraceptives are not associated with a decline in cervical cancer rates; in fact, long-term use of oral contraceptives is considered a mild risk factor for cervical cancer rather than a protective intervention.
B. Female circumcision has no evidence-based association with cervical cancer prevention and is not a recommended or ethical health-promoting intervention.
C. Vitamin supplementation has not been established as a primary intervention responsible for the decline in cervical cancer rates; while general nutrition supports immune function, it is not a direct preventive measure for cervical cancer.
Which factors are associated with cataracts? Select all that apply.
- Sudden vision loss.
- More common in young people.
- Excessive exposure to UV light is a risk factor.
- Cloudiness in the lens of the eye.
- Correctable with surgery.
Explanation
Explanation:
Correct Answers: (C) Excessive exposure to UV light is a risk factor, (D) Cloudiness in the lens of the eye, and (E) Correctable with surgery.
Cataracts are characterized by progressive clouding of the crystalline lens of the eye, which causes gradual blurring and dimming of vision. Prolonged exposure to ultraviolet light is a well-established modifiable risk factor for cataract development. Cataracts are the leading cause of correctable blindness worldwide and are treated effectively with surgical removal of the cloudy lens and replacement with an intraocular lens implant.
Why Options A and B are Incorrect:
A. Sudden vision loss is not characteristic of cataracts; cataract-related vision loss is gradual and progressive over months to years. Sudden vision loss is more indicative of retinal detachment, acute glaucoma, or vascular events.
B. Cataracts are primarily a condition of aging and are most common in older adults, not young people. While congenital cataracts can occur in children, the prevalence significantly increases with advancing age.
The registered nurse working in a COVID-19 triage unit reads vital signs taken by the patient care technician (PCT). Which patient should the nurse assess first?
- Mr. Grey: T 37.3°C P 96 R 18 BP 138/90 O2 Sat 97%
- Mr. Silver: T 37.4°C P 108 R 14 BP 102/74 O2 Sat 95%
- Mr. Green: T 36.8°C P 96 R 28 BP 118/68 O2 Sat 92%
- Mr. Brown: T 38°C P 100 R 16 BP 120/78 O2 Sat 99%
Explanation
Explanation:
Correct Answer: (C) Mr. Green: T 36.8°C P 96 R 28 BP 118/68 O2 Sat 92%
Mr. Green presents with a respiratory rate of 28 breaths per minute (tachypnea) and an oxygen saturation of 92%, both of which are critically abnormal, especially in a COVID-19 setting where respiratory compromise is the primary concern. Low O2 saturation combined with tachypnea signals impending respiratory failure and demands immediate assessment and intervention.
Why Other Options are Incorrect:
A. Mr. Grey — His vital signs are largely within normal limits. A slightly elevated blood pressure of 138/90 and O2 sat of 97% do not indicate an immediate emergency.
B. Mr. Silver — While his pulse of 108 is mildly elevated and O2 sat of 95% is slightly low, these findings are less critical compared to Mr. Green's respiratory distress indicators.
D. Mr. Brown — His temperature is slightly elevated but his O2 sat is 99% and all other vitals are within acceptable range, posing no immediate threat.
Which assessment finding could lead to undernutrition in the aging adult? Select all that apply.
- Poor dentition.
- Intact Cranial Nerve I.
- Decreased sense of smell.
- Receding gums.
- Increased saliva production.
Explanation
Explanation:
Correct Answers: (A) Poor dentition, (C) Decreased sense of smell, and (D) Receding gums.
Poor dentition impairs the ability to chew food properly, leading to avoidance of nutritious foods that are difficult to chew such as meats and raw vegetables. Decreased sense of smell reduces the enjoyment and appetite for food, leading to decreased food intake over time. Receding gums cause pain and difficulty with chewing, further limiting the types and amounts of food consumed, all contributing to undernutrition in the aging adult.
Why Options B and E are Incorrect:
B. Intact Cranial Nerve I (Olfactory) means the sense of smell is preserved, which would support rather than impair appetite and food intake, making it a protective factor rather than a risk for undernutrition.
E. Increased saliva production would facilitate chewing and swallowing, improving the ability to eat rather than contributing to undernutrition. In aging adults, decreased saliva production (xerostomia) is actually the more common problem that contributes to nutritional deficits.
The nurse is treating a patient diagnosed with the beginning stages of open-angle glaucoma. Which assessment data support this diagnosis?
- Impaired central vision.
- Impaired peripheral vision.
- Patient reports eye pain.
- Opacity of the lens.
Explanation
Explanation:
Correct Answer: (B) Impaired peripheral vision.
Open-angle glaucoma is characterized by a gradual, painless loss of peripheral (side) vision due to increased intraocular pressure that damages the optic nerve over time. Peripheral vision loss is typically the earliest and most characteristic finding of open-angle glaucoma, often going unnoticed by patients until significant damage has occurred.
Why Other Options are Incorrect:
A. Impaired central vision is more characteristic of advanced glaucoma or other conditions such as macular degeneration; central vision is typically preserved until the late stages of open-angle glaucoma.
C. Eye pain is characteristic of acute angle-closure glaucoma, which is a sudden onset emergency; open-angle glaucoma is typically painless, which is why it is often called the "silent thief of sight."
D. Opacity of the lens is the hallmark finding of cataracts, not glaucoma; glaucoma involves optic nerve damage from elevated intraocular pressure, not lens clouding.
During an assessment, the nurse notes a trachea that is deviated to the client's left side. Which condition is the most critical for the nurse to suspect and prioritize intervention for?
- Unilateral lymphadenopathy
- Goiter
- Cervical muscle spasm
- Tension pneumothorax on the right side
Explanation
Explanation:
Correct Answer: (D) Tension pneumothorax on the right side
A tension pneumothorax causes a mediastinal shift, pushing the trachea away from the affected side. If the trachea deviates to the left, the tension pneumothorax is on the right side. This is a life-threatening emergency requiring immediate intervention (needle decompression), making it the most critical condition to suspect.
Why Other Options are Incorrect:
A. Unilateral lymphadenopathy — Enlarged lymph nodes can occasionally cause mild tracheal deviation, but this is rarely an acute emergency and does not typically present as a critical condition requiring immediate prioritization.
B. Goiter — An enlarged thyroid can compress or displace the trachea, but this is usually a gradual process and does not represent an immediately life-threatening emergency in the way tension pneumothorax does.
C. Cervical muscle spasm — Muscle spasms may cause discomfort and limited neck movement, but they do not cause true tracheal deviation and are not a critical emergency condition.
