The polyneuropathic pattern of sensory loss suggests presence of the following syndrome:
- A. numbness & pain in distal parts of extremities
- B. numbness & analgesia in half of the body
- C. pain & sensory ataxia in half of the body
- D. analgesia & sensory ataxia in proximal parts of extremities
Correct Answer: A
Rationale: Numbness and pain in distal parts of extremities is the correct answer because polyneuropathy typically affects the longest nerves first, leading to a glove-and-stocking pattern of sensory loss. This condition is often caused by systemic diseases such as diabetes, vitamin deficiencies, or toxic exposures.

A technique that has proven to be helpful in training individuals with amnesia, where people are prevented - as far as possible - from making any errors while learning a new skill or new information is known as:
- A. Mnemonic training.
- B. Errorless learning.
- C. Aquistion learning.
- D. Prevention training.
Correct Answer: B
Rationale: Errorless learning is a training technique used to help individuals with amnesia acquire new skills or information without making mistakes. By minimizing errors during the learning process, this method enhances memory retention and reduces the likelihood of incorrect information being stored. Errorless learning is particularly effective for individuals with memory impairments, as it leverages their residual learning abilities and promotes successful skill acquisition.
While collecting data the nurse learns that a patient with a neurological illness has not had a sense of smell for several decades. Which part of the central nervous system should the nurse question as being damaged in this patient?
- A. Brainstem
- B. Occipital lobe
- C. Hypothalamus
- D. Temporal lobe
Correct Answer: D
Rationale: The olfactory nerve (cranial nerve I) originates in the temporal lobe, and damage to this area can result in anosmia (loss of smell). The brainstem, occipital lobe, and hypothalamus are not directly involved in the sense of smell. Assessing olfactory function can provide clues about neurological damage.
Before initiating levodopa for a client with Parkinson's disease, Nurse Allen ensures she is well-informed about the medication and its implications. What crucial information should Nurse Allen be aware of regarding levodopa?
- A. Levodopa's absorption can be insufficient if it is administered alongside meals.
- B. Levodopa has the potential to induce side effects such as orthostatic hypotension.
- C. Levodopa can lead to an initial feeling of euphoria, which is then followed by a phase of depression.
- D. Levodopa administration requires consistent monitoring through weekly laboratory tests.
Correct Answer: A
Rationale: Levodopa absorption is significantly reduced when taken with protein-rich meals, so it should be administered on an empty stomach or with a low-protein snack.
The nervous system is divided into the ___________.
- A. brain and spinal cord
- B. sympathetic and parasympathetic systems
- C. PNS & CNS
- D. autonomic and somatic nervous systems
Correct Answer: C
Rationale: The nervous system is broadly divided into the Central Nervous System (CNS), which includes the brain and spinal cord, and the Peripheral Nervous System (PNS), which includes all neural tissue outside the CNS. This division is fundamental to understanding the organization and function of the nervous system.
What is a nursing intervention that is indicated for the patient with hemiplegia?
- A. The use of a footboard to prevent plantar flexion
- B. Immobilization of the affected arm against the chest with a sling
- C. Positioning the patient in bed with each joint lower than the joint proximal to it
- D. Having the patient perform passive range of motion (ROM) of the affected limb with the unaffected limb
Correct Answer: A
Rationale: Using a footboard helps prevent contractures and deformities in patients with hemiplegia
