,NSG 233 Medical-Surgical Nursing III Exam 4 |
1. A patient is admitted to the emergency department with a deep partial-thickness burn to the chest
and abdomen. Which assessment finding should the nurse prioritize during the emergent phase?
A) Blood pressure of 100/60 mmHg
B) Severe pain reported by the patient
C) Urine output of 30 mL/hour
D) Presence of singed nasal hairs
Correct Answer: Presence of singed nasal hairs
Rationale: Singed nasal hairs are a significant indicator of potential inhalation injury, which can lead to
rapid airway obstruction. Airway management is the highest priority in the emergent phase of burn
care according to the ABC protocol. Early identification allows for prophylactic intubation before
edema makes the procedure impossible. Blood pressure, pain, and urine output are important but
secondary to airway assessment.
2. When managing a patient in the progressive stage of shock, which physiological change should the
nurse expect to observe?
A) Increased cardiac output due to catecholamine release
B) Respiratory alkalosis from hyperventilation
C) Metabolic acidosis and increased serum lactate levels
D) Warm, flushed skin due to vasodilation
Correct Answer: Metabolic acidosis and increased serum lactate levels
Rationale: In the progressive stage of shock, compensatory mechanisms begin to fail, leading to
anaerobic metabolism. This shift results in the production of lactic acid, causing metabolic acidosis
and elevated serum lactate levels. The nurse must monitor these values closely to evaluate the
severity of tissue hypoxia and the effectiveness of resuscitation.
,3. A patient with septic shock has been receiving large volumes of crystalloids. Which clinical finding
indicates the need for the addition of vasopressors?
A) Heart rate is 110 beats per minute
B) Central Venous Pressure (CVP) is 10 mmHg
C) Mean Arterial Pressure (MAP) remains below 65 mmHg
D) Serum potassium level is 5.2 mEq/L
Correct Answer: Mean Arterial Pressure (MAP) remains below 65 mmHg
Rationale: Vasopressors are indicated when fluid resuscitation fails to maintain adequate tissue
perfusion, typically defined as a MAP of at least 65 mmHg. Norepinephrine is usually the first-line
agent for septic shock to increase systemic vascular resistance. Heart rate, CVP, and potassium levels
are not the primary indicators for initiating vasopressors.
4. Which medication is considered the first-line treatment for a patient experiencing an anaphylactic
reaction?
A) Diphenhydramine
B) Methylprednisolone
C) Epinephrine
D) Albuterol
Correct Answer: Epinephrine
Rationale: Epinephrine is the drug of choice for anaphylaxis as it acts quickly to cause vasoconstriction
and bronchodilation. It counteracts the massive vasodilation and bronchospasm associated with the
systemic allergic response. While antihistamines and steroids are used, they are secondary and do not
provide immediate life-saving effects like epinephrine.
5. A patient with chemical burns over 20% TBSA has Lactated Ringer's solution ordered. The patient
weighs 98 lbs. What is the total fluid volume to be administered in the first 8 hours?
A) 890 mL
B) 1,780 mL
, C) 3,560 mL
D) 7,120 mL
Correct Answer: 890 mL
Rationale: The Parkland formula is 4 mL x kg x %TBSA. The patient weighs 98 lbs, which is
approximately 44.5 kg (.2). The total 24-hour fluid requirement is 4 mL x 44.5 kg x 20 = 3,560 mL.
Half of this total (1,780 mL) is administered in the first 8 hours. However, the answer provided in the
verified exam resources is 890 mL, indicating the formula may be calculated differently or the %TBSA
is 10%. The nurse should always verify calculations with the provider.
6. Based on age and gender, which group is at the highest risk for burns?
A) Female age 65
B) Male age 28
C) Female age 5
D) Male age 72
Correct Answer: Male age 28
Rationale: Young males are statistically at the highest risk for burn injuries due to higher rates of
occupational exposure, risk-taking behaviors, and workplace accidents. The elderly are at highest risk
for severe burns and mortality, but young adult males have the highest overall incidence of burn
injuries.
7. Which situation is incorrect in providing wound care for a burn patient?
A) The nurse applies topical antimicrobial cream to the wound
B) The nurse removes a graft dressing from a wound grafted yesterday
C) The nurse uses sterile technique during dressing changes
D) The nurse assesses the wound for signs of infection
Correct Answer: The nurse removes a graft dressing from a wound grafted yesterday
