Free ATI Nursing 531 Exam Questions
A patient tells the nurse that he has noticed that one of his moles has started to burn and bleed. The nurse should be concerned with which additional finding
-
A lesion that is symmetric
-
Irregular edges of the lesion
-
Lesion diameter less than 6 mm
-
Consistent color of the lesion
Explanation
Correct Answer B: Irregular edges of the lesion
Explanation:
Irregular or poorly defined borders are one of the warning signs of malignant melanoma, a serious form of skin cancer. When combined with symptoms like burning and bleeding, this finding raises concern for possible malignancy and warrants immediate medical evaluation.
Why the other options are incorrect:
A) A lesion that is symmetric:
Symmetry is a good sign. Asymmetry, not symmetry, is concerning.
C) Lesion diameter less than 6 mm:
Moles larger than 6 mm are more suspicious. A smaller lesion is less worrisome unless other changes are present.
D) Consistent color of the lesion:
Multiple or uneven colors (brown, black, red, white, blue) are concerning. Uniform color is generally a benign feature.
The physician ordered Amoxicillin 10 mg IM every 6 hours. Amoxicillin is supplied in 125 mg per 5 ml. How many milliliters will the nurse administer per dose
-
0.4 ml
-
0.2 ml
-
1 ml
-
0.5 ml
Explanation
Correct Answer A: 0.4 ml
Explanation:
To calculate the volume to administer, use the formula:
(Desired dose÷Available dose)×Available volume(\text{Desired dose} ÷ \text{Available dose}) × \text{Available volume}(Desired dose÷Available dose)×Available volume (10mg÷125mg)×5ml=0.08×5=0.4ml(10 mg ÷ 125 mg) × 5 ml = 0.08 × 5 = 0.4 ml(10mg÷125mg)×5ml=0.08×5=0.4ml
So, the nurse will give 0.4 ml per dose.
Why the other options are incorrect:
B) 0.2 ml: Too low — incorrect calculation.
C) 1 ml: Would deliver 25 mg, more than double the ordered amount.
D) 0.5 ml: Would give 12.5 mg, which exceeds the prescribed 10 mg.
What component of the conduction system is referred to as the pacemaker of the heart
-
Bundle branches
-
Bundle of His
-
Purkinje fibers
-
Sinoatrial (SA) node
Explanation
Correct Answer D: Sinoatrial (SA) node
Explanation:
The SA node, located in the right atrium, is known as the natural pacemaker of the heart. It initiates electrical impulses that set the rhythm for the entire heart, typically generating 60–100 beats per minute in a healthy adult.
Why the other options are incorrect:
A) Bundle branches:
These conduct impulses from the Bundle of His down the ventricles, but they do not generate the heart's rhythm.
B) Bundle of His:
This structure conducts impulses from the atria to the ventricles but does not act as the primary pacemaker.
C) Purkinje fibers:
These fibers distribute the electrical impulse through the ventricles, causing contraction, but they only take over pacing if higher centers fail, and at a slower rate.
A teen mother is inspecting her infant two days after delivery and says to the nurse, "I noticed that my baby has this spot that is soft on the top of her head. Is something terribly wrong?" What is the nurse's best response
-
Perhaps that could be a result of your dietary intake during pregnancy.
-
That 'soft spot' may be an indication of cretinism or congenital hypothyroidism
-
That 'soft spot' is normal, and allows brain growth during your baby's first year of life.
-
Your baby may have craniosynostosis, a disease of the sutures of the brain
Explanation
Correct Answer C: That 'soft spot' is normal, and allows brain growth during your baby's first year of life.
Explanation:
The "soft spot" the mother is referring to is the anterior fontanel, a normal anatomical feature in newborns. It allows for expansion of the brain during rapid growth in the first year of life and typically closes by 12–18 months of age. Reassurance and education are appropriate.
Why the other options are incorrect:
A) Perhaps that could be a result of your dietary intake during pregnancy
This is speculative and not relevant to the normal presence of a fontanel.
B) That 'soft spot' may be an indication of cretinism or congenital hypothyroidism.
While delayed closure of fontanels may be associated with certain conditions, the presence of a soft spot in a 2-day-old infant is normal.
D) Your baby may have craniosynostosis, a disease of the sutures of the brain.
Craniosynostosis involves premature fusion of sutures—not a soft spot—and typically presents with abnormal head shape, not a normal fontanel.
During a health history, a 22-year old woman asks, "Can I get that vaccine for human papilloma virus (HPV)? I have genital warts and I'd like them to go away!"
What is the nurse's best response
-
Let's check with the physician to see if you are a candidate for this vaccine.
-
This vaccine is only for girls who have not yet started to become sexually active
-
The vaccine cannot protect you now that you already have an HPV infection
-
The HPV vaccine is for girls and women ages 9 to 26 years, so we can start that today
Explanation
Correct Answer D: The HPV vaccine is for girls and women ages 9 to 26 years, so we can start that today.
Explanation:
The HPV vaccine is recommended for females and males aged 9 to 26, and it can still be given to individuals who already have HPV or genital warts. While the vaccine will not treat existing warts or infections, it can protect against other strains of the virus that the individual has not yet been exposed to. The patient, being 22 years old, is within the eligible age range and can benefit from vaccination.
Why the other options are incorrect:
A) Let's check with the physician to see if you are a candidate for this vaccine.
While not harmful, this is a vague and non-committal answer. The nurse should provide accurate, evidence-based guidance within their scope of practice.
B) This vaccine is only for girls who have not yet started to become sexually active.
This is incorrect. Although the vaccine is most effective when given before sexual activity begins, it is still recommended for individuals up to age 26, even if they are already sexually active.
C) The vaccine cannot protect you now that you already have an HPV infection.
This is false. The vaccine does not treat existing infections, but it can still offer protection against other strains of HPV that the person hasn’t contracted yet.
The nurse is preparing for a certification course on skin care and needs to be familiar with the various lesions that may be identified on assessment of the skin. Which of the following definitions are correct
-
Macule: Discolored, flat lesion not larger than 1 cm
-
Papule: Hypertrophic scar
-
Bulla: Elevated, circumscribed lesion filled with pus
-
Nodule: Solid, elevated growth larger than 1 cm
- Vesicle: Blister not larger than 1 cm
Explanation
Correct Answers:
A) Macule: Discolored, flat lesion not larger than 1 cm
D) Nodule: Solid, elevated growth larger than 1 cm
E) Vesicle: Blister not larger than 1 cm
Explanation:
A) Macule: A macule is a flat, non-palpable area of skin discoloration that is less than or equal to 1 cm in diameter. Examples include freckles and flat moles.
D) Nodule: A nodule is a solid, elevated lesion larger than 1 cm, often extending into the dermis or subcutaneous tissue. Examples include lipomas.
E) Vesicle: A vesicle is a small, fluid-filled blister, not larger than 1 cm, and contains clear serous fluid. Common in conditions like chickenpox or herpes simplex.
Why the other options are incorrect:
B) Papule: Hypertrophic scar – Incorrect. A papule is a small, raised lesion less than 1 cm in diameter, such as a wart. A hypertrophic scar is an overgrowth of scar tissue and is not classified as a papule.
C) Bulla: Elevated, circumscribed lesion filled with pus – Incorrect. A bulla is a fluid-filled (serous) blister larger than 1 cm, not filled with pus. A pustule is the correct term for a pus-filled lesion.
The nurse is assessing the apical pulse of a 3-month-old infant and finds that the heart rate is 135 beats per minute. How should the nurse interpret this finding
-
Higher than expected, reflecting persistent tachycardia
-
Normal for this age
-
Higher than expected, probably as a result of crying
-
Lower than expected
Explanation
Correct Answer B: Normal for this age
Explanation:
The normal apical heart rate for a 3-month-old infant ranges from approximately 100 to 160 beats per minute when awake. A heart rate of 135 bpm is within the normal range and does not indicate tachycardia or bradycardia.
Why the other options are incorrect:
A) Higher than expected, reflecting persistent tachycardia:
135 bpm is not considered tachycardia for a 3-month-old.
C) Higher than expected, probably as a result of crying:
Although crying can raise heart rate, 135 bpm is still normal even without crying.
D) Lower than expected:
135 bpm is not too low; in fact, it's right in the expected range.
A mother brings her 3-month-old infant to the clinic for evaluation of a cold. She tells the nurse that he has had "a runny nose for a week." When performing the physical assessment, the nurse notes that the child has nasal flaring and sternal and intercostal retractions. What should the nurse do next
-
Recognize that these are serious signs, and contact the physician.
-
Ask the mother if the infant has had trouble with feedings.
-
Assure the mother that these signs are normal symptoms of a cold.
-
Perform a complete cardiac assessment because these signs are probably indicative of early heart failure.
Explanation
Correct Answer A: Recognize that these are serious signs, and contact the physician.
Explanation:
Nasal flaring and sternal/intercostal retractions are signs of respiratory distress in infants. These findings indicate that the infant is working hard to breathe and may be deteriorating quickly. This requires immediate medical evaluation and intervention. The nurse should not delay and must promptly notify the physician or advanced care provider.
Why the other options are incorrect:
B) Ask the mother if the infant has had trouble with feedings:
While feeding difficulty is important, the priority is to address the infant's respiratory distress immediately.
C) Assure the mother that these signs are normal symptoms of a cold:
This is incorrect and dangerous—these are not normal cold symptoms in an infant and could signal a life-threatening issue.
D) Perform a complete cardiac assessment because these signs are probably indicative of early heart failure:
Though cardiac issues can cause similar symptoms, these signs more commonly suggest acute respiratory distress, and immediate respiratory evaluation is the priority.
Which of the following best reflects characteristics of an expert nurse
-
Uses a well-defined set of rules in order to make clinical decisions.
-
Uses step-by-step decision-making process when deciding to act.
-
Uses intuition to recognize patterns and act without consciously labeling it.
-
Uses established protocols that tell how to provide patient care.
Explanation
Correct Answer C: Uses intuition to recognize patterns and act without consciously labeling it.
Explanation:
An expert nurse, according to Benner’s Novice to Expert model, relies on deep experience and intuitive understanding of clinical situations. They quickly recognize patterns and respond appropriately without needing to rely on rules or step-by-step procedures.
Why the other options are incorrect:
A) Uses a well-defined set of rules:
This reflects the behavior of a novice or advanced beginner, not an expert.
B) Uses step-by-step decision-making process:
Typical of a competent nurse who is still learning to prioritize and make decisions methodically.
D) Uses established protocols:
This applies more to proficient or competent nurses still building their clinical judgment through guidelines.
The nurse is listening to the breath sounds of a patient with severe asthma. Air passing through narrowed bronchioles would produce which of these adventitious sounds
-
Bronchophony
-
Rales
-
Wheezes
-
Crackles
Explanation
Correct Answer C: Wheezes
Explanation:
Wheezes are high-pitched, musical sounds heard primarily during expiration and are caused by air passing through narrowed or constricted airways, as seen in conditions like asthma, bronchitis, or COPD. They indicate airway obstruction.
Why the other options are incorrect:
A) Bronchophony:
Not a breath sound—it's a voice sound test used to assess lung consolidation, not a direct result of airflow through bronchioles.
B) Rales:
An older term for crackles, which are heard with fluid in the alveoli, such as in pneumonia or heart failure—not airway narrowing.
D) Crackles:
Heard during inspiration and caused by popping open of collapsed alveoli or fluid, not from narrowed bronchioles as seen in asthma.
