Question 1 of 9
The nurse understands that an anaphylactic reaction is considered which of the following types of hypersensitivity reactions?
Correct Answer: A
Rationale: The correct answer is A: Type I hypersensitivity reaction. In Type I hypersensitivity, anaphylactic reactions involve immediate IgE-mediated responses to allergens, leading to histamine release and potentially life-threatening symptoms. This type of reaction is characterized by rapid onset and systemic involvement. Choices B, C, and D are incorrect because Type III reactions involve immune complex deposition leading to inflammation (B), Type II reactions involve cytotoxic antibodies targeting cells (C), and Type IV reactions involve delayed cell-mediated responses (D).
Question 2 of 9
A nurse approaches a hospitalized poststroke patient from the patient’s left side to do an assessment. The patient is staring straight ahead, and does not respond to the nurse’s presence or voice. Which action should the nurse take first?
Correct Answer: A
Rationale: Rationale: 1. By approaching the patient from the other side, the nurse can assess if the patient has a visual field deficit. 2. This step helps determine if the lack of response is due to a sensory issue. 3. It allows the nurse to rule out unilateral neglect or hemianopsia. 4. Walking to the other side is a basic assessment technique to evaluate visual and sensory deficits in poststroke patients. Other Choices: B. Speaking more loudly and clearly may not address the potential sensory issues the patient is experiencing. C. Waving fingers in front of the patient's face does not provide a comprehensive assessment of visual field deficits. D. Using a picture may be helpful, but addressing the potential visual field deficit should be prioritized first.
Question 3 of 9
While obtaining a health history, the nurse learns that the client is allergic to bee stings. When obtaining the client’s medication history, the nurse should determine if the client keeps which medication on hand?
Correct Answer: A
Rationale: Rationale: A: Diphenhydramine hydrochloride (Benadryl) is an antihistamine commonly used to treat allergic reactions, including those from bee stings. It can help alleviate symptoms like itching and swelling. Keeping Benadryl on hand is crucial for managing an allergic reaction promptly. Other Choices: B: Guaifenesin (Robitussin) is an expectorant used to treat coughs, not allergic reactions. C: Pseudoephedrine hydrochloride (Sudafed) is a decongestant used for nasal congestion, not allergic reactions. D: Loperamide (Imodium) is an antidiarrheal used to treat diarrhea, not allergic reactions.
Question 4 of 9
A client with advanced breast cancer is prescribed tamoxifen (Nolvadex). When teaching the client about this drug, the nurse should emphasize the importance of reporting which adverse reaction immediately?
Correct Answer: A
Rationale: The correct answer is A: Vision changes. Tamoxifen can cause serious ocular side effects like retinopathy and corneal changes. These adverse reactions can lead to vision impairment or loss, which is crucial to report immediately to prevent permanent damage. Headache (B), hearing loss (C), and anorexia (D) are not typically associated with tamoxifen use and do not pose immediate threats to the client's health compared to vision changes. It is important for the nurse to prioritize educating the client on recognizing and reporting vision changes promptly to ensure timely intervention and prevent irreversible consequences.
Question 5 of 9
Which drug class is used to reduce symptoms of muscle weakness from myasthenia gravis?
Correct Answer: A
Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.
Question 6 of 9
Clinical manifestations of Huntington’s disease include:
Correct Answer: D
Rationale: The correct answer is D because Huntington's disease is a neurodegenerative disorder that presents with a triad of symptoms: abnormal involuntary movements (chorea), intellectual decline, and emotional disturbances. Abnormal involuntary movements are a hallmark feature, while cognitive decline and emotional disturbances are also commonly observed. Therefore, all three manifestations are typically present in individuals with Huntington's disease. Choices A, B, and C are incorrect because each of these symptoms alone does not encompass the full spectrum of clinical manifestations seen in Huntington's disease.
Question 7 of 9
Which of the ff. descriptions by the nurse would best explain glaucoma to a patient?
Correct Answer: B
Rationale: The correct answer is B: "There is an increase in the intraocular pressure." Glaucoma is a group of eye conditions that damage the optic nerve due to increased pressure within the eye. High intraocular pressure is a key factor in the development of glaucoma. Choice A is incorrect because glaucoma is not associated with an increase in vitreous humor. Choice C is incorrect as glaucoma is not related to a decrease in aqueous humor. Choice D is incorrect because glaucoma is characterized by an increase, not a decrease, in intraocular pressure. Therefore, the most accurate description to explain glaucoma to a patient is the one that mentions the increase in intraocular pressure.
Question 8 of 9
Which of the following would be the most appropriate nursing intervention when caring for a client with a fractured rib?
Correct Answer: A
Rationale: Correct Answer: A - Apply immobilization device after examination by physician Rationale: 1. Immobilization helps reduce pain and prevent further injury. 2. Physician examination ensures proper diagnosis and treatment plan. 3. Immobilization device may include chest binders or splints for support. 4. It is crucial to follow medical advice to prevent complications. Summary: B: Discouraging deep breaths can lead to respiratory complications. C: Advising against analgesics can increase pain and hinder recovery. D: Increased fluid intake is important but not directly related to rib fracture care.
Question 9 of 9
The client is taking phenyton (Dilantin) for seizure control. A sample is drawn to determine the serum drug level, and the nurse reviews the results. Which of the following would indicate a therapeutic serum drug range?
Correct Answer: A
Rationale: The correct answer is A (5 to 10 mcg/ml) because this range is typically considered therapeutic for phenytoin (Dilantin) for seizure control. Levels below 5 mcg/ml may be subtherapeutic, leading to inadequate seizure control. Levels above 10 mcg/ml can increase the risk of toxicity. Choices B, C, and D are incorrect because they are outside the optimal therapeutic range, leading to either ineffective treatment (B, C) or an increased risk of adverse effects (D). Monitoring drug levels helps ensure the medication's effectiveness while minimizing side effects.
