HESI Pediatric (N158) Exam

The correct answer is D: Balance on one foot for a few seconds

Explanation:

At 3 years old, a child typically begins to develop better balance and coordination. They can balance on one foot for a brief moment (a few seconds), which is an expected milestone for their gross motor development.

Why the other options are incorrect:

A. Jump rope:

Jumping rope is usually a skill that develops later, around 5-6 years old, when children have better coordination and rhythm.

B. Ride a two-wheel bicycle:

Riding a two-wheel bicycle usually comes around 5-6 years old, when children have better control over balance and pedaling. At age 3, children may begin to use a tricycle, but not a two-wheel bike.

C. Skip on alternate feet:

Skipping typically emerges around 4 years old, as it requires more advanced coordination and motor skills than what is typically seen in 3-year-olds, who are still mastering simpler movements like walking and running.

Summary:

At 3 years old, a child should be able to balance on one foot for a few seconds, which demonstrates emerging balance and coordination. Skills like jumping rope, riding a two-wheel bicycle, and skipping develop later in childhood.

The correct answer is D: They can be easily aspirated.

Explanation:

Peanuts are not recommended as a snack for toddlers primarily because they pose a significant choking and aspiration hazard. Toddlers do not yet have the fully developed chewing and swallowing coordination needed to safely handle small, hard foods like whole peanuts. If inhaled or swallowed incorrectly, peanuts can block the airway, leading to serious injury or even death from aspiration.

Why the other options are incorrect:

A. They are low in nutritive value:

Peanuts actually have a high nutritive value—they are a good source of protein, healthy fats, and fiber. Nutrition is not the concern; safety is.

B. They are very high in sodium:

While some processed peanut products may contain added salt, whole peanuts themselves are not particularly high in sodium, and sodium content is not the primary concern with peanuts for toddlers.

C. They cannot be entirely digested:

This is not accurate. Peanuts are digestible, though they may be harder for some toddlers to break down due to limited chewing ability. However, this is not the main reason they are unsafe—the main concern is aspiration risk, not digestion.

Summary:

The nurse should recommend avoiding peanuts as a snack for toddlers because they can be easily aspirated, posing a serious choking hazard. Safe snack options should be soft, easy to chew, and age-appropriate to prevent injury.

The correct answer is A: Before chest physiotherapy (CPT)

Explanation:

Aerosolized bronchodilator medications should be administered before chest physiotherapy (CPT) in children with cystic fibrosis (CF). The purpose of the bronchodilator is to open the airways and help the child breathe more easily by relaxing the muscles around the airways. This allows the chest physiotherapy (which includes techniques like percussion and vibration to help loosen mucus) to be more effective in clearing mucus from the lungs. Administering the bronchodilator first ensures the airways are more open, improving the effectiveness of CPT.

Why the other options are incorrect:

B. After CPT:

Administering bronchodilators after CPT is not recommended, as the airways are not optimally open to help with mucus clearance. The bronchodilator should be given beforehand to maximize the effectiveness of chest physiotherapy.

C. Before receiving 100% oxygen:

While oxygen therapy is important for CF patients, it is not directly related to the timing of bronchodilator administration. The bronchodilator should be given before CPT, regardless of oxygen administration, to ensure the airways are open for better mucus clearance.

D. After receiving 100% oxygen:

The bronchodilator should not be delayed until after oxygen therapy. Oxygen can help improve oxygenation, but bronchodilators are best administered before CPT to prepare the airways for effective mucus clearance.

Summary:

The correct timing for administering aerosolized bronchodilators in children with cystic fibrosis is before chest physiotherapy (CPT) to open the airways and enhance the effectiveness of the therapy. Therefore, A. Before chest physiotherapy (CPT) is the correct answer.

The correct answer is A: Pressure the victim into secrecy

Explanation:

One of the most common characteristics of individuals who sexually abuse children is that they pressure, manipulate, or coerce the victim into keeping the abuse a secret. Abusers often use threats, bribes, shame, guilt, or emotional manipulation to ensure the child does not disclose the abuse. This secrecy helps the abuser continue the behavior undetected, sometimes for long periods.

Why the other options are incorrect:

B. Are usually unemployed and unmarried:

There is no specific employment or marital status profile for abusers. Sexual abusers of children come from all backgrounds, occupations, and family situations. Many are employed and may even appear to be well-integrated in their communities.

C. Are unknown to victims and victims' families:

Most often, abusers are known to the child and their family. They may be relatives, family friends, teachers, coaches, or caregivers. Stranger abuse is less common than abuse by someone familiar and trusted.

D. Have many victims that are each abused only once:

Child sexual abuse often involves repeated abuse of the same victim rather than one-time abuse of many victims. The abuser may work to establish a relationship of trust or dependency to maintain ongoing access to the child.

Summary:

The most common characteristic of child sexual abusers is that they pressure the victim into secrecy, which allows the abuse to continue and often go undetected.

The correct answer is A: There is heightened airway reactivity.

Explanation:

Bronchial asthma is characterized by increased airway reactivity, meaning that the airways are more likely to constrict in response to triggers such as allergens, cold air, or respiratory infections. This heightened reactivity leads to bronchoconstriction, inflammation, and excess mucus production, which cause the hallmark symptoms of asthma, such as wheezing, shortness of breath, chest tightness, and coughing. This characteristic is the most accurate and descriptive feature of asthma.

Why the other options are incorrect:

B. There is decreased resistance in the airway:

This is incorrect. In asthma, there is increased airway resistance due to bronchoconstriction, inflammation, and mucus production, not decreased resistance. This increased resistance leads to difficulty in breathing and airflow limitation.

C. The single cause of asthma is an allergic hypersensitivity:

While allergic hypersensitivity is a common trigger for asthma, it is not the single cause. Asthma can be triggered by a variety of factors, including environmental pollutants, infections, exercise, and cold air. Genetic predisposition and environmental factors play significant roles in the development of asthma.

D. It is inherited:

Asthma can have a genetic component, but it is not solely inherited. Family history plays a role in susceptibility, but environmental factors and other triggers also contribute to the development of asthma.

Summary:

The most accurate description of bronchial asthma is that there is heightened airway reactivity, leading to airway narrowing and breathing difficulties. Therefore, the correct answer is A. There is heightened airway reactivity.

The correct answer is B: Parent to stabilize the chin with one hand and brush with the other.

Explanation:

At a toddler's age, they typically do not have the dexterity to effectively clean all surfaces of their teeth, and they also may not have the attention span or understanding to brush thoroughly. Therefore, it’s important for the parent to assist with brushing by stabilizing the child’s chin and using the other hand to brush the teeth properly. This ensures that all surfaces are cleaned effectively, including hard-to-reach areas like the back teeth.

Why the other options are incorrect:

A. Child to brush regularly with toothpaste of his or her choice:

While it’s important for toddlers to begin learning how to brush, they lack the coordination and skill to brush effectively at this age. A parent should assist and supervise brushing until the child can do it more independently (usually around age 6 or 7).

C. Parent to brush the mandibular occlusive surfaces, leaving the rest for the child:

While it’s important for the parent to help, leaving the rest for the child can result in ineffective cleaning. Toddlers often cannot reach all areas of their teeth, including the sides and back. The parent should assist with brushing all surfaces to ensure thorough cleaning.

D. Parent to brush the front labial surfaces, leaving the rest for the child:

Similarly to option C, leaving any surfaces for the child to clean is not effective, as toddlers often struggle with brushing all the surfaces of their teeth. The parent should help brush all areas to ensure a complete cleaning.

Summary:

The most effective way to clean a toddler's teeth is for the parent to stabilize the child's chin with one hand and use the other to brush all surfaces of the teeth, ensuring thorough cleaning and good dental hygiene.

The correct answer is A: 5 mm

Explanation:

For individuals who are HIV positive, a 5 mm or greater induration is considered a positive result on the tuberculin skin test (TST). This is because people with HIV have a weakened immune system, and they are at higher risk for developing active tuberculosis (TB), even with smaller amounts of exposure. The threshold for a positive result is lower in immunocompromised individuals compared to healthy individuals, where a larger induration (10 mm or more) would be needed to indicate a positive test.

Why the other options are incorrect:

B. 10 mm:

A 10 mm induration is generally considered positive for individuals without HIV or other risk factors (such as recent TB exposure). However, for HIV-positive individuals, a 5 mm induration is considered positive.

C. 15 mm:

A 15 mm induration is typically considered positive for individuals who are at low risk for TB, such as healthy adults with no known risk factors. This size is too large for an HIV-positive individual, where a 5 mm induration is the threshold.

D. 20 mm:

A 20 mm induration is definitely positive, but it is much larger than the threshold required for a positive result in an HIV-positive person. A 5 mm induration is sufficient to indicate a positive result for someone with HIV.

Summary:

For an adolescent who is HIV-positive, a 5 mm or greater induration is considered positive for tuberculosis on the tuberculin skin test. Therefore, the correct answer is A. 5 mm.

The correct answer is A: Prolonged exhalations.

Explanation:

A. Prolonged exhalations:

This finding requires immediate intervention because prolonged exhalations can indicate respiratory distress or obstruction, such as in conditions like asthma, bronchiolitis, or other respiratory issues. This may suggest that the child is having difficulty expelling air from the lungs, which could be a sign of a serious respiratory problem. Immediate assessment and intervention are crucial to ensure the child’s airway is not compromised.

B. Thick yellow rhinorrhea:

While thick yellow rhinorrhea is often associated with a bacterial infection, it is not typically a critical finding requiring immediate intervention in the context of triage. It can be a symptom of a viral upper respiratory infection (such as the common cold) or bacterial sinusitis, which, while requiring treatment, does not usually demand urgent action.

C. Frequent nonproductive cough:

A nonproductive cough is a common symptom of upper respiratory infections, viral illnesses, or even allergies. While it is uncomfortable and may indicate infection, it generally does not require immediate intervention unless accompanied by severe respiratory distress or other concerning signs.

D. Oxygen saturation is 95% by pulse oximeter:

An oxygen saturation of 95% is within normal limits for most children, and does not indicate a need for immediate intervention unless it drops below 92% or the child is showing signs of respiratory distress. It’s essential to monitor oxygen levels, but at 95%, there is no immediate need for intervention.

Summary:

The nurse should prioritize prolonged exhalations as it suggests respiratory distress or difficulty, requiring immediate assessment and intervention. This could indicate a significant problem with the child's airway or lung function that needs urgent attention.

The correct answer is D: Periodically for children who reside in high-prevalence regions.

Explanation:

The Mantoux tuberculin skin test (TST) is used to detect latent tuberculosis infection (LTBI). Skin testing is recommended periodically for children who are at higher risk of exposure to tuberculosis, particularly those who live in or travel to high-prevalence areas, or who have close contact with someone known to have active tuberculosis. Routine annual testing for all children is not recommended unless they are in a high-risk category.

Why the other options are incorrect:

A. Every year for all children older than 2 years:

Routine annual testing for all children over 2 years is not recommended. The Mantoux test is typically performed based on risk factors, such as exposure to high-risk populations or living in areas with higher tuberculosis rates, not as a routine screening for all children.

B. Every year for all children older than 10 years:

Routine yearly testing for all children over 10 years is also not recommended. As with younger children, testing should be based on risk factors for tuberculosis exposure, not on age alone.

C. Every 2 years for all children starting at age 1 year:

There is no guideline that recommends testing every 2 years for all children starting at age 1. Skin testing should be risk-based, performed periodically for those at risk of tuberculosis exposure, rather than on a set schedule for all children.

Summary:

Skin testing for tuberculosis (the Mantoux test) is recommended periodically for children who reside in high-prevalence regions or have other risk factors for exposure, rather than being performed annually or at regular intervals for all children. This ensures testing is focused on those most at risk for tuberculosis infection.
