1. While assisting with data collection, the nurse asks the client to close their jaws tightly. Subsequently, the nurse tries to open the closed jaws. In this technique, the nurse is assessing the motor function of which nerve?
- A. Trochlear nerve
- B. Abducens nerve
- C. Trigeminal nerve
- D. Oculomotor nerve
Correct answer: C
Rationale: The correct answer is C: Trigeminal nerve. To test the motor function of the trigeminal nerve (cranial nerve V), the nurse assesses the muscles of mastication by asking the client to clench their teeth. By trying to separate the client's jaws, the nurse evaluates the strength of the temporal and masseter muscles innervated by the trigeminal nerve. This technique helps assess if the trigeminal nerve is functioning properly. Choices A, B, and D are incorrect because they relate to other cranial nerves that are not involved in the specific motor function being tested in this scenario. These nerves are usually assessed through different examinations such as assessing the pupils and extraocular movements, which are not part of the jaw clenching and opening technique described in the question.
2. When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?
- A. Iris
- B. Cornea
- C. Optic disc
- D. Conjunctiva
Correct answer: C
Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope. Therefore, the correct answer is the optic disc. Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.
3. A healthcare professional reviewing the health care record of a client notes documentation of grade 4 muscle strength. The healthcare professional understands that this indicates:
- A. Full ROM with gravity
- B. Full ROM against gravity with full resistance
- C. Full ROM with gravity eliminated (passive motion)
- D. Full ROM against gravity with some resistance
Correct answer: D
Rationale: Muscle strength is graded on a scale of 0 to 5. A grade of 5 indicates normal strength and is described as full ROM against gravity with full resistance. Grade 4 indicates good strength and full ROM against gravity with some resistance. Grade 3 indicates fair strength and full ROM with gravity. Grade 2 indicates poor strength and full ROM with gravity eliminated (passive motion). Grade 1 indicates trace strength and slight contraction. Grade 0 indicates zero strength and no contraction. Therefore, the correct answer is 'Full ROM against gravity with some resistance.' Choices A, B, and C are incorrect as they do not match the description of muscle strength associated with a grade of 4.
4. An allergic reaction is classified as what type of pharmacological effect?
- A. a therapeutic effect
- B. a side effect
- C. an adverse effect
- D. an incompatibility
Correct answer: C
Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.
5. When assessing a client with deep pitting edema, with the indentation remaining for a short time and visible leg swelling, how should a nurse document this finding?
- A. 1+ edema
- B. 2+ edema
- C. 3+ edema
- D. 4+ edema
Correct answer: C
Rationale: The correct answer is 3+ edema. When assessing for edema, the nurse presses thumbs against the ankle malleolus or the tibia. If the skin retains an indentation, it indicates pitting edema. The grading scale for pitting edema includes: 1+ for mild pitting with slight indentation and no perceptible leg swelling, 2+ for moderate pitting where the indentation subsides rapidly, 3+ for deep pitting with an indentation remaining briefly and visible leg swelling, and 4+ for very deep pitting with a long-lasting indentation and significant leg swelling. Choices A, B, and D do not accurately represent the severity of the edema described in the scenario.
