-
Sex assigned male at birth
-
Hispanic race
-
Full-term birth
-
Being first-born
-
Having young parents younger than 20 years old
Explanation
Infants assigned male at birth are four to five times more likely to develop IHPS than female infants, making biological sex one of the strongest known risk factors for this condition.
Being first-born is a well-established risk factor for IHPS. First-born children have a statistically higher incidence of pyloric stenosis compared to subsequent siblings, though the exact reason is not fully understood.
Why the other options are incorrect:
B. Hispanic race IHPS is more commonly seen in White infants of Northern European descent. Hispanic race is not identified as an increased risk factor for this condition.
C. Full-term birth Gestational age at birth is not a significant risk factor for IHPS. Both full-term and preterm infants can develop pyloric stenosis, and full-term birth alone does not increase the risk.
E. Having young parents younger than 20 years old Parental age is not a recognized risk factor for infantile hypertrophic pyloric stenosis. The condition is associated with genetic and anatomical factors rather than the age of the parents.
-
The client has a history of receiving a transfusion with Rh-negative blood.
-
The client's blood contains the Rh factor and the newborn's does not, and antibodies that destroy red blood cells are formed in the fetus.
-
The client's anti-A and anti-B antibodies cross the placenta and cause the destruction of the fetal red blood cells.
-
The client's blood does not contain the Rh factor, so she produces anti-Rh antibodies that cross the placental barrier and cause hemolysis of red blood cells in newborns.
Explanation
In Rh incompatibility, the mother is Rh-negative and the fetus is Rh-positive. When fetal Rh-positive red blood cells enter the maternal circulation during delivery or other sensitizing events, the Rh-negative mother produces anti-Rh antibodies. In subsequent pregnancies, these antibodies cross the placenta and attack the Rh-positive fetal red blood cells, causing hemolysis. The breakdown of these red blood cells releases bilirubin, resulting in hyperbilirubinemia and hemolytic disease of the newborn.
Why the other options are incorrect:
A. The client has a history of receiving a transfusion with Rh-negative blood. Sensitization occurs when an Rh-negative person is exposed to Rh-positive blood, not Rh-negative blood. Receiving Rh-negative blood would not trigger anti-Rh antibody production as there is no foreign Rh antigen present.
B. The client's blood contains the Rh factor and the newborn's does not, and antibodies that destroy red blood cells are formed in the fetus. This reverses the actual mechanism. It is the Rh-negative mother who lacks the Rh factor and produces antibodies, not the other way around. The fetus does not produce the destroying antibodies.
C. The client's anti-A and anti-B antibodies cross the placenta and cause the destruction of the fetal red blood cells. Anti-A and anti-B antibodies describe ABO incompatibility, which is a separate condition from Rh incompatibility. These are different blood group systems with distinct mechanisms of hemolytic disease.
-
Diminished deep-tendon reflexes
-
Respiratory rate of 16/min
-
Heart rate of 56/min
-
Urine output of 50 mL in 4hr
Explanation
Correct Answer: (B) Respiratory rate of 16/min
A respiratory rate of 16/min is within the normal range of 12 to 20/min and indicates that magnesium sulfate has not caused respiratory depression. A respiratory rate of at least 12/min is required to safely continue the magnesium sulfate infusion. This is a key safety parameter monitored during magnesium therapy.
Why the other options are incorrect:
A. Diminished deep-tendon reflexes Diminished or absent deep-tendon reflexes are an early sign of magnesium toxicity. Normal or present deep-tendon reflexes are required before continuing the infusion. Loss of patellar reflex indicates dangerous magnesium levels and warrants stopping the infusion immediately.
C. Heart rate of 56/min A heart rate of 56/min indicates bradycardia, which can be a sign of magnesium toxicity affecting cardiac conduction. Normal heart rate must be maintained during magnesium sulfate therapy, and bradycardia warrants withholding the infusion and notifying the provider.
D. Urine output of 50 mL in 4hr Adequate urine output during magnesium sulfate therapy should be at least 25 to 30 mL/hr or 100 mL in 4 hours. An output of only 50 mL in 4 hours indicates oliguria, which reduces magnesium excretion and increases the risk of toxicity, requiring the infusion to be held and the provider notified.
-
Undergoing current treatment for HIV.
-
Personal history of alcohol use disorder.
-
Family history of Alzheimer's disease.
-
Current rehabilitation for opiate addiction.
Explanation
Wernicke-Korsakoff syndrome is caused by severe thiamine (vitamin B1) deficiency, most commonly resulting from chronic alcohol use disorder. Alcohol impairs thiamine absorption, reduces dietary intake, and depletes thiamine stores, leading to the neurological damage characteristic of this syndrome including confusion, ataxia, ophthalmoplegia, and severe memory impairment.
Why the other options are incorrect:
A. Undergoing current treatment for HIV. While HIV and its treatments can cause neurological complications, HIV is not a primary cause of Wernicke-Korsakoff syndrome. This condition is specifically linked to thiamine deficiency rather than viral infection.
C. Family history of Alzheimer's disease. Wernicke-Korsakoff syndrome is not a hereditary condition and is not linked to Alzheimer's disease. While both conditions affect memory, they have entirely different etiologies and mechanisms.
D. Current rehabilitation for opiate addiction. Opiate addiction does not directly cause thiamine deficiency in the same manner as alcohol use disorder. While poor nutrition can occur with any substance use disorder, Wernicke-Korsakoff syndrome is specifically and predominantly associated with alcohol use disorder.
Medical History
Client has a history of type 2 diabetes mellitus, chronic kidney disease, and hemodialysis with arteriovenous fistula.
Nurses' Notes
Day 1, 1000:
Client alert and oriented x3. Lung fields clear, heart rhythm regular; bowel sounds normoactive x4; ate 75% of morning meal. Denies pain. Left forearm arteriovenous (AV) fistula, skin warm, brachial and radial pulses 2+.
Day 1, 1600:
Client returned from dialysis, lethargic, not hungry, tried to eat a few crackers but vomited them up. Capillary blood glucose 134 mg/dL. AV fistula site skin warm, bruit and thrill noted, brachial and radial pulses palpable.
Day 2, 0700:
Client reports not sleeping well last night; capillary blood glucose 75 mg/dL; crackles in left lower lobe; unproductive cough; AV fistula site ecchymotic, warm, bruit and thrill noted. Oriented to person, place, and time.
Vital Signs
Day 1, 1000: Temperature 36.3° C (97.3° F) Heart rate 70/min Respiratory rate 16/min Blood pressure 144/72 mm Hg Oxygen saturation 94% on room air Weight 90 kg (198 lb)
Day 1, 1600: Temperature 37.1° C (98.7° F) Heart rate 62/min Respiratory rate 16/min Blood pressure 112/54 mm Hg Oxygen saturation 95% on room air
Day 2, 0700: Temperature 36.7° C (98.1° F) Heart rate 62/min Respiratory rate 12/min Blood pressure 118/52 mm Hg Oxygen saturation 95% on room air Weight 86.4 kg (190 lb)
A nurse is caring for a client who has received hemodialysis. Which of the following assessment findings require follow-up?
-
Vital signs
-
Weight
-
Blood glucose level
-
Presence of bruit and thrill
-
Lung sounds
-
AV fistula site assessment
Explanation
Correct Answers: (B) Weight, (C) Blood glucose level, (E) Lung sounds, (F) AV fistula site assessment
Weight decreased from 90 kg on Day 1 to 86.4 kg on Day 2, a loss of 3.6 kg (approximately 8 lbs) over a short period. While hemodialysis removes fluid, this degree of weight loss combined with the client's lethargy, vomiting, and inability to eat requires follow-up to assess for excessive fluid removal and potential hypovolemia.
Blood glucose level of 75 mg/dL on Day 2 represents a significant drop from 134 mg/dL on Day 1 at 1600 and is approaching hypoglycemia, particularly concerning given the client's history of type 2 diabetes mellitus, poor oral intake, and vomiting. This requires immediate follow-up and monitoring.
Lung sounds showing crackles in the left lower lobe on Day 2 are a new finding not present on Day 1. Crackles indicate fluid accumulation in the lungs, which may represent pulmonary edema, pneumonia, or atelectasis and require prompt follow-up and provider notification.
AV fistula site showing ecchymosis on Day 2 is a new finding compared to the warm, intact site on Day 1. Ecchymosis at the fistula site may indicate bleeding, hematoma formation, or vascular complications that could compromise the fistula's function and the client's dialysis access, requiring immediate assessment.
Why Other Options are Incorrect:
A. Vital signs The vital signs across all three time points do not show critical abnormalities requiring urgent follow-up. The blood pressure decreased after dialysis which is expected, heart rate and respiratory rate are within acceptable ranges, temperature remains normal, and oxygen saturation is stable at 95%.
D. Presence of bruit and thrill The bruit and thrill are consistently present and noted on both Day 1 and Day 2, confirming the AV fistula is patent and functioning. This is a reassuring finding and does not require follow-up as a problem.
-
Increased muscle mass
-
Increased balance
-
Increased joint stiffness
-
Increased calcification of bones
Explanation
Correct Answer: (C) Increased joint stiffness
Increased joint stiffness is a normal and expected age-related change resulting from the deterioration of cartilage, decreased synovial fluid production, and reduced elasticity of connective tissues surrounding the joints. This leads to decreased range of motion and increased stiffness, particularly in the morning or after periods of inactivity.
Why the other options are incorrect:
Aging is associated with sarcopenia, which is the progressive loss of muscle mass and strength. Older adults experience decreased muscle mass rather than an increase, due to hormonal changes, decreased physical activity, and reduced protein synthesis.
Balance typically declines with age due to deterioration of vestibular function, proprioception, vision, and muscle strength. Older adults are at significantly increased risk for falls due to decreased balance, not improved balance.
While bone calcification sounds like it would increase bone density, aging is actually associated with decreased bone density and increased porosity, leading to osteoporosis. Older adults experience net bone resorption exceeding bone formation, resulting in weaker and more fracture-prone bones rather than increased calcification.
-
Aversion to being touched
-
Childhood obesity
-
Impulsive actions
-
Lethargy
Explanation
Correct Answer: (C) Impulsive actions
Impulsivity is one of the three core symptom categories of ADHD, along with inattention and hyperactivity. Children with ADHD frequently act without thinking, interrupt others, have difficulty waiting their turn, and engage in risky behaviors without considering consequences. Impulsive actions are a hallmark and expected clinical finding in ADHD.
Why the other options are incorrect:
Aversion to tactile stimulation is more commonly associated with sensory processing disorders or autism spectrum disorder, not ADHD. While ADHD and autism can coexist, aversion to being touched is not a defining feature of ADHD.
While some research suggests a association between ADHD and obesity related to impulsive eating behaviors, childhood obesity is not a clinical manifestation or expected assessment finding of ADHD itself. It is not among the diagnostic criteria for the disorder.
Lethargy, or abnormal fatigue and decreased activity, is the opposite of what is expected in ADHD. Children with ADHD typically present with hyperactivity, restlessness, and excessive energy rather than lethargy.
-
Identify genetic factors that influence opiate withdrawal.
-
Analyze and interpret laboratory and medical imaging data.
-
Determine the client's risk of developing severe manifestations.
-
Assess severity of symptoms from withdrawal and treat accordingly.
Explanation
Correct Answer: (D) Assess severity of symptoms from withdrawal and treat accordingly.
The Clinical Opiate Withdrawal Scale (COWS) is a validated 11-item assessment tool used by clinicians to measure the severity of opiate withdrawal symptoms in real time. The score obtained guides clinical decision-making regarding the need for and dosing of medications such as buprenorphine to manage withdrawal symptoms appropriately and safely.
Why Other Options are Incorrect:
A. Identify genetic factors that influence opiate withdrawal. The COWS is a clinical observation and symptom-rating tool, not a genetic assessment instrument. It does not evaluate or identify genetic predispositions or factors related to opiate metabolism or withdrawal susceptibility.
B. Analyze and interpret laboratory and medical imaging data. The COWS is entirely based on observable clinical signs and the client's self-reported symptoms. It does not incorporate laboratory values or imaging studies into its scoring or purpose.
C. Determine the client's risk of developing severe manifestations. The COWS assesses current symptom severity rather than predicting future risk of severe withdrawal. It measures what the client is experiencing at the time of assessment, not what they may develop later.
-
Vitamin C
-
Sodium
-
Vitamin K
-
Potassium
Explanation
Correct Answer: (B) Sodium
Lithium and sodium compete for reabsorption in the renal tubules. When sodium intake is low or the client is dehydrated, the kidneys reabsorb more lithium to compensate for the sodium deficit, leading to dangerously elevated lithium levels and toxicity. Clients must maintain a consistent and adequate dietary sodium intake to keep lithium levels stable and within the therapeutic range.
Why Other Options are Incorrect:
A. Vitamin C Vitamin C is an antioxidant important for immune function and collagen synthesis but has no direct interaction with lithium metabolism or renal handling. It does not affect lithium levels and is not a dietary priority specific to lithium therapy.
C. Vitamin K Vitamin K is essential for blood clotting and is a dietary consideration for clients on warfarin therapy, not lithium. There is no clinically significant interaction between vitamin K intake and lithium levels or toxicity.
D. Potassium While potassium is important for cardiac and neuromuscular function, it does not affect lithium reabsorption or serum lithium levels in the way sodium does. Potassium intake is not a specific dietary teaching priority for clients on lithium therapy.
-
Gray umbilical cord
-
Moist skin
-
Protruded abdomen
-
Wide skull sutures
Explanation
In SGA newborns, intrauterine growth restriction leads to delayed bone ossification and reduced bone growth, resulting in wide skull sutures. This occurs because the skull bones do not grow and fuse at the normal rate due to inadequate nutrition and growth in utero.
Why the other options are incorrect:
A. Gray umbilical cord A normal umbilical cord appears yellow-green or bluish-white at birth. A gray umbilical cord is not a characteristic finding of SGA and may instead suggest infection or other pathology.
B. Moist skin SGA newborns typically have dry, loose, peeling skin due to decreased subcutaneous fat and reduced vernix caseosa. Moist skin is not an expected finding in this condition.
C. Protruded abdomen SGA newborns tend to have a scaphoid or sunken abdomen due to decreased muscle mass and fat stores from intrauterine growth restriction, not a protruded abdomen.
