HESI LPN
HESI PN Exit Exam 2023
1. The nurse is teaching a client with diabetes mellitus how to differentiate between hypoglycemia and ketoacidosis. What statement indicates to the nurse that the client has an understanding of this condition?
- A. Glucose should be taken if I have a fruity breath odor.
- B. Glucose should be taken if I am urinating more than usual.
- C. Glucose should be taken if I have blurred vision.
- D. Glucose should be taken if I develop shakiness.
Correct answer: D
Rationale: The correct answer is D. Shakiness is a symptom of hypoglycemia, which is low blood sugar. Taking glucose can help raise blood sugar levels quickly in this situation. Fruity breath odor and excessive urination are signs of ketoacidosis, a complication of diabetes involving high levels of ketones in the blood. Blurred vision can be a symptom of high blood sugar, but it is not specific to hypoglycemia.
2. A nurse is inspecting the skin of a child with atopic dermatitis. What would the nurse expect to observe?
- A. Erythematous papulovesicular rash
- B. Dry, red, scaly rash with lichenification
- C. Pustular vesicles with honey-colored exudates
- D. Hypopigmented oval scaly lesions
Correct answer: B
Rationale: In atopic dermatitis, the characteristic presentation includes a dry, red, scaly rash with lichenification. This appearance is due to chronic inflammation and scratching. Choice A is incorrect as erythematous papulovesicular rash is more indicative of conditions like contact dermatitis. Choice C is incorrect as pustular vesicles with honey-colored exudates are seen in impetigo. Choice D is incorrect as hypopigmented oval scaly lesions are more characteristic of tinea versicolor.
3. What instructions should the PN reinforce with the client regarding the newly prescribed medications isosorbide dinitrate and hydrochlorothiazide?
- A. Instruct the client to use a soft bristle toothbrush.
- B. Instruct the client to slowly rise from a sitting or lying down position.
- C. Instruct the client to elevate their legs above the level of their heart.
- D. Instruct the client to limit the amount of fiber in their diet.
Correct answer: B
Rationale: The correct instruction for the client is to slowly rise from a sitting or lying down position. Isosorbide dinitrate, a nitrate, and hydrochlorothiazide, a diuretic, can both cause hypotension. When used together, their additive effects can further lower blood pressure, leading to orthostatic hypotension. Instructing the client to change positions slowly helps prevent a sudden drop in blood pressure, reducing the risk of dizziness or falls. Choices A, C, and D are incorrect because they do not directly address the potential side effect of hypotension associated with the prescribed medications. Using a soft bristle toothbrush, elevating legs above the heart level, or limiting fiber intake are not specific instructions to mitigate the risk of orthostatic hypotension.
4. While caring for a client with an AV fistula in the left forearm, the nurse observed a palpable buzzing sensation over the fistula. What action should the nurse take?
- A. Loosen the dressing of the fistula
- B. Report the presence of a bounding pulse
- C. Document that the fistula is intact
- D. Apply gentle pressure over the site
Correct answer: C
Rationale: The correct answer is C: Document that the fistula is intact. The palpable buzzing sensation (known as a thrill) over the AV fistula indicates proper functioning. It is essential for the nurse to document this finding to ensure ongoing monitoring of the fistula's status. Choices A, B, and D are incorrect. Choice A is incorrect because there is no indication to loosen the dressing. Choice B is incorrect as a bounding pulse is not associated with the palpable buzzing sensation of a thrill. Choice D is incorrect as applying pressure over the site is not necessary for this situation.
5. During postoperative care for a child who has had a tonsillectomy, what is an important nursing intervention?
- A. Encouraging deep breathing exercises
- B. Encouraging the child to eat
- C. Administering antibiotics
- D. Applying ice to the throat
Correct answer: C
Rationale: Administering antibiotics is crucial post-tonsillectomy to prevent infection, as the surgical site is susceptible to bacterial growth. Encouraging deep breathing exercises can also be beneficial for lung expansion and preventing respiratory complications. However, administering antibiotics takes precedence as it directly addresses the risk of infection. Encouraging the child to eat may not be appropriate immediately post-tonsillectomy due to the risk of throat irritation and potential discomfort. Applying ice to the throat is typically not recommended after a tonsillectomy, as it may constrict blood vessels and hinder the healing process.
