Complete the following sentence/sentences by choosing from the list/lists of options.The licensed practical nurse should assist the registered nurse to prepare the client for emergency--------------------------
- A. colonoscopy
- B. CT angiography
- C. Esophagogastroduodenoscopy
Correct Answer: C
Rationale: The nurse should assist in preparing the client for emergency esophagogastroduodenoscopy (EGD). An EGD involves
passing an endoscope down the esophagus to visualize the upper gastrointestinal (Gl) structures (eg, esophagus, stomach,
duodenum), identify the source of the bleed, and perform interventions to stop the bleeding (eg, hemostatic clipping). To
prepare the client for EGD, the nurse should ensure NPO status has been initiated to reduce the risk of aspiration.
Interventions to stabilize the client (eg, IV fluids, blood transfusion) are often initiated before EGD.

The nurse is reinforcing teaching to the client and the parents about management of type 1 diabetes mellitus and prescribed insulin therapy. For each potential instruction, click to specify whether the instruction is appropriate or not appropriate to
include in the teaching
- A. Track carbohydrate intake
- B. Rotate insulin injection sites
- C. Wear a medical alert bracelet
- D. Demonstrate insulin injections on a doll
- E. Store unopened insulin vials at room temperature
Correct Answer:
Rationale: Type 1 diabetes mellitus (DM) is characterized by insulin deficiency and management requires insulin therapy for blood glucose
control. The nurse should provide dietary teaching and instructions for insulin administration. Appropriate instructions to
include in the teaching include:
• Track carbohydrate intake to guide insulin administration and maintain blood glucose levels. Exogenous insulin
administration increases the risk of hypoglycemia. Carbohydrate intake should be relatively consistent each day to avoid
hyperglycemia or hypoglycemia.
• Rotate insulin injection sites to prevent tissue scarring or loss of subcutaneous tissue (ie, lipoatrophy).
• Wear a medical alert bracelet to indicate type 1 DM in the event of hypoglycemia and unconsciousness.
• Demonstrate insulin injections on a doll before performing injections on the child to help prepare the client and family.
Insulin vials that remain unopened should be stored in the refrigerator until opened and can be used up to the expiration date.
Once opened, the vial can be stored at room temperature for approximately 1 month. Injections are less painful when the vial
is stored at room temperature, and lipodystrophy is less likely. Storing the unopened vials at room temperature is not
appropriate to include in the teaching
The nurse has reviewed the information from the Nurses' Notes, Vital Signs, and Laboratory Results.The nurse is reviewing the client's response to potassium-lowering therapies. Which finding is unexpected and requires follow-up by the
nurse?
- A. Blood glucose level and diaphoresis
- B. Blood pressure and heart rate
- C. Crackles and peripheral edema
- D. Serum potassium level
Correct Answer: A
Rationale: Treatment for hyperkalemia includes administration of calcium gluconate, furosemide, albuterol nebulizer, and insulin with dextrose. These
therapies may cause rapid shifts in fluid volume, blood glucose, and serum electrolytes. Insulin shifts available glucose and potassium into
the cell, lowering serum potassium levels; however, too much insulin and not enough dextrose cause hypoglycemia (eg, blood glucose 50
mg/dL [2.7 mmol/L]). Clients with kidney disease have an increased risk of hypoglycemia because insulin may accumulate.
The nurse should understand that a low blood glucose level and symptoms suspicious for hypoglycemia (eg, diaphoresis) require follow-u
to prevent seizures, coma, and death due to lack of circulating glucose (Option 1). This client requires an additional dose of dextrose.
(Option 2) This client's blood pressure is 146/88 mm Hg and heart rate is within normal limits. This is an improvement from the initial blood
pressure and represents a therapeutic response to furosemide administration. Blood pressure should be lowered slowly to avoid hypotensior
The nurse has reviewed the information from the Laboratory Results and Nurses' Notes. Which of the following nursing actions are anticipated? Select all that apply
- A. Adds 5% dextrose to continuous IV fluids
- B. Administers potassium chloride
- C. Administers sodium bicarbonate
- D. Discontinues insulin infusion
- E. Encourages the client to drink orange juice
Correct Answer: A,B
Rationale: The goal of treatment of diabetic ketoacidosis (DKA) is to normalize fluid volume, decrease blood glucose levels, balance electrolytes, and
correct metabolic acidosis. On administration of insulin, potassium and glucose shift from the extracellular space to the intracellular space.
Clients with DKA require potassium administration due to low intracellular potassium levels.
Insulin is administered to facilitate glucose transport into the intracellular space to resolve DKA and should be continued until the metabolic
acidosis resolves. When caring for clients with DKA, the nurse should anticipate:
• Adding 5% dextrose to continuous IV fluids when the serum blood glucose level reaches approximately 200 mg/dL (11.1 mmol/L) to
prevent hypoglycemia and cerebral edema resulting from levels decreasing too quickly (Option 1). This is done because insulin is still
required to resolve DKA. If the DKA is resolved, insulin can also be decreased instead of adding dextrose to the IV fluids.
• Administering potassium chloride for a client with hypokalemia and adequate urine output (ie, >30 mL/hr) to prevent life-threatening
arrhythmias
The nurse is caring for a 42-year-old client in the emergency department. The nurse is reviewing the collected client data to assist with preparing the client's plan of care. Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to measure the client's progress.
- A. Administer phenytoin, Discontinue sertraline, Administer methimazole, Administer a benzodiazepine, Prepare to administer radioactive iodine
- B. Panic attack, Hyperthyroidism, Serotonin syndrome, Neuroleptic malignant syndrome
- C. Clonus, TSH level, WBC count, Temperature, Feelings of impending doom
Correct Answer:
Rationale: Serotonin syndrome (ie, serotonin toxicity) is a life-threatening condition caused by excess serotonin in the central nervous
system. Tramadol is an analgesic medication with serotonergic activity that can lead to serotonin syndrome when taken with a
selective serotonin reuptake inhibitor (eg, sertraline).
Clinical manifestations include mental status changes (eg, anxiety, restlessness, agitation), autonomic dysregulation (eg,
diaphoresis, tachycardia, hypertension, hyperthermia), and neuromuscular hyperactivity. Treatment involves discontinuing all
serotonergic medications (eg, sertraline, tramadol) and administering a benzodiazepine to improve agitation and
decrease muscle contraction (eg, clonus), which reduces temperature.
The nurse has reviewed the information from the Laboratory Results. Which of the following conditions should the nurse suspect? Select all that apply.
- A. Attention deficit hyperactivity disorder
- B. Major depressive disorder
- C. Posttraumatic stress disorder
- D. Schizophrenia
- E. Substance use disorder
Correct Answer: B,E
Rationale: Major depressive disorder (MDD) is characterized by a persistent (duration ≥2 weeks) depression in mood (eg, sadness,
social withdrawal) that interferes with daily life. This client has several clinical manifestations of MDD, including loss of interest
in daily activities, significant change in appetite or weight, persistent feelings of worthlessness, recurrent thoughts of self-harm,
inattention, and fatigue. MDD is a significant risk factor for suicide
Substance use disorder is the recurrent use of alcohol and/or recreational drugs that results in interpersonal dysfunction,
impaired control, and physical effects (eg, withdrawal). This client's urine drug screen is positive for cocaine and marijuana
Therefore, the nurse should further investigate the client's substance use (eg, amount, frequency, route of administration, date
of last use, perceived benefits, negative consequences)
