The nurse is preparing to administer the first dose of the prescribed IVPB antibiotic. Which 2 actions are most appropriate for the nurse to perform prior to initiating the infusion?

A. Administer a dose of PRN acetaminophen
B. Ask about the client's medication allergies
C. Ensure that prescribed blood cultures have been obtained
D. Ensure that the prescribed echocardiography has been obtained
E. Reschedule the antibiotic dose until the central venous catheter is in place

Correct Answer: B,C

Rationale: Antibiotic therapy is a critical component of treatment for clients with infective endocarditis (E). Before administering IV
antibiotics, the nurse should first obtain blood cultures to identify the infectious organism. Broad-spectrum antibiotics are
started initially. Targeted antibiotic therapy can be administered once the blood cultures identify the culprit organisms and their
antimicrobial susceptibilities. Before starting any medication, the nurse should ask about the client's medication allergies to
identify contraindications to therapy

The nurse has reviewed the information from the Laboratory Results. Complete the following sentence/sentences by choosing from the list/lists of options.The nurse should prioritize interventions to treat ------------ due to the risk of ---------------------.

A. Hyperkalemia
B. Dysrhythmias
C. Elevated BUN
D. Seizures
E. Hyponatremia
F. Acute kidney injury

Correct Answer: A,B

Rationale: The client's laboratory results show hyperkalemia (ie, high potassium) and decreased kidney function, seen as elevated BUN and creatinine.
The kidneys balance potassium levels by eliminating excess potassium through urine. Clients with heart failure (HF) are at an increased risk fo
hyperkalemia due to poor kidney perfusion from decreased cardiac output and medication adverse effects. This client's decreased kidney
function and home medications, including lisinopril (ACE inhibitor) and supplemental potassium chloride, all increase the risk of hyperkalemia.
Because potassium is responsible for myocardial cell repolarization, hyper- or hypokalemia may lead to life-threatening dysrhythmias.
Therefore, the nurse should prioritize interventions to treat hyperkalemia due to the risk of dysrhythmias.

Select 5 findings that require immediate follow-up.

A. sore throat and nasal congestion for the past week
B. Pregnancy status is
unknown.
C. The abdomen is soft without rigidity or
rebound tenderness,
D. appears drowsy and is oriented to person and time on
E. Vital signs are T 98.8 F (37.1 C), V P 128, V RR 30, and BP 88/60 mm Hg
F. Finger-stick blood glucose level is 600 mg/dL (33.3 mmol/L) .

Correct Answer: B,D,E,F

Rationale: This client has findings of chronic hyperglycemia, including polydipsia (increased thirst) and polyuria (increased urination) which may indicate
untreated diabetes mellitus. Recent findings also indicate potential upper respiratory infection, hypovolemia, and an acute abdominal
condition. For this client, the following findings are the priority for follow-up:
• Delayed menstruation (time since last menstruation exceeds typical cycle length) could indicate that the client is pregnant, which
presents a risk for pregnancy-related complications (eg, ruptured ectopic pregnancy) and affects care provided to the client (eg, avoid x-
rays and teratogenic medications).
• Decreased level of consciousness (eg, drowsiness, disorientation) places the client at increased risk for injury and aspiration and
may indicate impaired brain perfusion. This may be due to hypotension or hyperglycemia-induced cerebral edema.
• Hypotension causes impaired organ perfusion that could be life threatening without immediate intervention.
• Tachycardia occurs to compensate for hypotension or can be the cause of hypotension and requires prompt attention to prevent
cardiovascular collapse.
• Tachypnea is concerning, particularly when associated with rapid, deep respirations (ie, Kussmaul breathing), because it may indicate a
compensatory response to an underlying metabolic acidosis (eg, ketoacidosis, hypotension-induced lactic acidosis).
• Severe hyperglycemia may indicate diabetic ketoacidosis (DKA), a life-threatening complication of diabetes mellitus. In addition,
hyperglycemia has a diuretic effect leading to fluid loss that worsens cardiovascular compromise.

Complete the following sentence by choosing from the lists of options. Based on the clinical findings, the client is most at risk for--------------------- as evidenced by the client's------------------------

A. vital signs
B. peritonitis and sepsis
C. fluid volume deficit and hypovolemic shock
D. abdominal pain
E. date of last menstrual period
F. intraabdominal hemorrhage and hypovolemic shock

Correct Answer: C,A

Rationale: The client's findings are most aligned with diabetic ketoacidosis (DKA). When there is a lack of insulin to transport glucose into cells, glucose
accumulates, creating an osmotic gradient that leads to diuresis (polyuria) and fluid loss. If the hyperglycemia persists, the process continues
and the fluid volume deficit decreases cardiac output and perfusion to vital organs (hypotension). The heart rate increases (tachycardia)
to compensate for the decrease in cardiac output. Without immediate treatment, compensatory mechanisms eventually fail, and the client is
at risk for developing life-threatening hypovolemic shock

The client is diagnosed with autism spectrum disorder (ASD). The nurse recognizes that clients with ASD are at risk for which of the following complications? Select all that apply.

A. Impaired interpersonal relationships
B. Learning difficulties
C. Malnutrition
D. Self-harm behaviors
E. Sleep disturbances

Correct Answer: A,BC,D,E

Rationale: Autism spectrum disorder (ASD) begins in the developmental period, and symptoms tend to persist throughout the lifespan.
Clients with ASD are more prone to medical, psychiatric, and psychosocial impairments. These impairments include the
following:
• Impaired interpersonal relationships: Clients with ASD may be disinterested in social interaction and have difficulty
showing affection and interpreting conversation
• Learning difficulties: Clients with ASD may have trouble focusing on tasks and have a limited range of learning
interests (eg, preferring only math), making it challenging to engage them in other areas of learning (Option 2).
• Malnutrition: Clients with ASD can have a narrowed interest in foods, resulting in insufficient intake of necessary
nutrients. In addition, clients with ASD often experience gastrointestinal disturbances, including constipation and
diarrhea, due to narrowed food intake
• Self-harm behaviors: Changes in routine and environment can trigger repetitive or harmful behaviors (eg, head-
banging, hand-biting). When self-harm behaviors persist into adulthood, they may be preceded by suicide attempts
related to coexisting psychiatric comorbidities (eg, depression, anxiety)
• Sleep disturbances: Clients with ASD often experience difficulty falling and staying asleep. Hyperresponsiveness to
sensory stimulation (eg, lights, noises, sensations) can also contribute to disruptive sleeping patterns

The nurse is caring for a 65-year-old client in the clinic. Complete the following sentence by choosing from the list of options.The nurse suspects that the clients condition is most likely related to the abrupt discontinuation of-----------------

A. Lisinopril
B. Metoprolol
C. Atorvastatin

Correct Answer: B

Rationale: Beta-adrenergic antagonists, also known as beta blockers (eg, metoprolol, atenolol), are commonly used to treat
hypertension, heart failure, and anxiety. Beta blockers reduce cardiac workload by inhibiting the action of catecholamines (eg,
epinephrine, norepinephrine) on beta-adrenergic receptors in the heart. This slows electrical conduction through the heart,
which decreases heart rate and blood pressure.
Abrupt discontinuation of beta blockers can result in rebound hypertension, angina, palpitations, myocardial infarction,
arrhythmias (eg, tachycardia, ventricular tachycardia), or sudden death. These discontinuation-associated risks are caused
by increased beta-adrenergic receptor sensitivity to circulating catecholamines, resulting in an increased sympathetic
response. Withdrawal symptoms should resolve after resumption of the medication.
