HESI RN CAT Exit Exam
1. A client with type 2 diabetes mellitus is admitted for antibiotic treatment of a leg ulcer. Which signs and symptoms, indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS), should the nurse report to the healthcare provider? (Select one that doesn't apply.)
- A. Increased heart rate
- B. Visual disturbances
- C. Presence of uremic frost
- D. Decreased mentation
Correct answer: C
Rationale: The correct answer is C, 'Presence of uremic frost.' Increased heart rate, visual disturbances, and decreased mentation are all signs and symptoms indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS). Uremic frost, however, is not associated with HHNS but is a clinical finding seen in severe cases of chronic kidney disease. Therefore, the nurse should report the presence of uremic frost to the healthcare provider as a separate concern from HHNS.
2. The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory result requires immediate intervention?
- A. Blood glucose of 250 mg/dL.
- B. Serum potassium of 3.5 mEq/L.
- C. Serum sodium of 135 mEq/L.
- D. Arterial blood pH of 7.30.
Correct answer: D
Rationale: An arterial blood pH of 7.30 indicates the client is in acidosis, which is a life-threatening condition in DKA. Immediate intervention is required to correct the acidosis and prevent further complications such as organ failure or coma. Blood glucose of 250 mg/dL is elevated but not an immediate threat to life in comparison to acidosis. Serum potassium of 3.5 mEq/L and serum sodium of 135 mEq/L are within normal ranges and do not warrant immediate intervention in the context of DKA.
3. A client has a prescription for albuterol (Proventil HFA) (two puffs) and beclomethasone dipropionate (Qvar) (nasal inhalation, two puffs) by metered-dose inhaler. The medications are to be administered by the nurse by giving the:
- A. Albuterol first and then the beclomethasone dipropionate
- B. Beclomethasone dipropionate first and then the albuterol
- C. Alternating a single puff of each, beginning with the albuterol
- D. Alternating a single puff of each, beginning with the beclomethasone dipropionate
Correct answer: A
Rationale: Albuterol, as a bronchodilator, should be administered first to help open up the airways, followed by beclomethasone dipropionate to reduce inflammation in the airways. This sequence ensures optimal therapeutic effects of the medications.
4. An overweight client taking warfarin (Coumadin) has dry skin due to decreased arterial blood flow. What should the nurse instruct the client to do? Select all that apply.
- A. Apply lanolin or petroleum jelly to intact skin.
- B. Follow a reduced-calorie, reduced-fat diet.
- C. Inspect the involved areas daily for new ulcerations.
- D. Instruct the client to limit activities of daily living (ADLs).
Correct answer: A
Rationale: To address dry skin and prevent chronic ulcers and infections in an overweight client on warfarin with decreased arterial blood flow, the nurse should instruct the client to apply lanolin or petroleum jelly to intact skin. This helps maintain skin integrity and moisture. Following a reduced-calorie, reduced-fat diet (Choice B) may be beneficial for weight management but is not directly related to skin care. Inspecting involved areas daily for new ulcerations (Choice C) is important for skin assessment and early intervention but does not specifically address dry skin. Instructing the client to limit activities of daily living (ADLs) (Choice D) is not necessary for addressing dry skin; in fact, promoting mobility and circulation through appropriate activities is crucial.
5. A clinic nurse prepares to administer an MMR (measles, mumps, rubella) vaccine to a child. How is this vaccine best administered?
- A. Intramuscularly in the deltoid muscle
- B. Subcutaneously in the gluteal muscle
- C. Subcutaneously in the outer aspect of the upper arm
- D. Intramuscularly in the anterolateral aspect of the thigh
Correct answer: C
Rationale: The MMR vaccine is best administered subcutaneously in the outer aspect of the upper arm. This route allows for proper absorption and efficacy of the vaccine while minimizing the risk of injury or discomfort to the child.
