Nursing Process Exam Questions

Correct Answer: D

Rationale: The correct answer is D: Hypomagnesemia. Dehydration can lead to electrolyte imbalances, and hypomagnesemia can cause confusion in elderly patients. Magnesium plays a crucial role in brain function and its deficiency can result in cognitive impairment. Hyponatremia (A) typically presents with symptoms like weakness and confusion but not necessarily dehydration. Hypercalcemia (B) and hyperkalemia (C) are less likely to cause confusion in this scenario. Therefore, hypomagnesemia is the most likely electrolyte imbalance involved in the elderly nursing home resident's confusion.

Correct Answer: B

Rationale: Step 1: Guillain-Barre Syndrome (GBS) is characterized by a rapid onset of weakness and tingling sensations in the legs. Step 2: Paresthesia refers to abnormal sensations like tingling or numbness, which is a common initial neurological symptom of GBS. Step 3: Absent tendon reflexes may occur in GBS due to muscle weakness but are not typically the initial symptom. Step 4: Dysrhythmias and transient hypertension are not typical symptoms of GBS and are not associated with its initial presentation. In summary, choice B is correct as paresthesia of the legs is a hallmark initial neurological symptom of Guillain-Barre Syndrome, while choices A, C, and D are incorrect as they do not align with the typical presentation of GBS.

Correct Answer: B

Rationale: The correct answer is B because the client remains radioactive for a period of time after the implant removal, typically around 10 days. During this time, the nurse should take precautions to limit exposure to radiation. Choice A is incorrect because bodily fluids are not highly radioactive, and proper disposal procedures should be followed. Choice C is incorrect as soiled linens should be handled appropriately to prevent contamination. Choice D is incorrect as bed rest may not be necessary, and mobility should be encouraged within safety guidelines.

Correct Answer: C

Rationale: The normal range of hemoglobin in adult blood is typically between 12-18 g/dL. This range is the most common and widely accepted range based on clinical guidelines and research studies. Hemoglobin levels outside this range may indicate anemia or other health conditions. Choice A (7-11 mg) is too low for normal hemoglobin levels in adults and indicates severe anemia. Choice B (14-20 mg) is slightly higher and could be normal for some individuals, but generally, 12-18 g/dL is the standard range. Choice D (20-26 mg) is too high and may indicate dehydration or other medical conditions.

Correct Answer: A

Rationale: The correct answer is A: Applying the liquid test antigen. During a scratch test to detect allergies, the nurse's role is to apply the liquid test antigen onto the skin to observe the body's reaction. This antigen contains potential allergens that may trigger a response in allergic individuals. By applying this antigen, the nurse can assess if the patient develops a raised wheal or redness at the site, indicating an allergic reaction. This step is crucial in identifying specific allergens causing the patient's symptoms. Choices B, C, and D are incorrect as determining the type of allergy, measuring the length and width of the reaction, and documenting the findings are all important steps but do not directly relate to the initial action of applying the test antigen during a scratch test.
