Which of the following parts of neuron transmits impulses away from the cell body?
- A. Dendrite
- B. Neurolemma
- C. Axon
- D. Synapse
Correct Answer: C
Rationale: The axon is the part of the neuron that transmits impulses away from the cell body. It is a long, slender extension of the neuron that conducts electrical signals known as action potentials to other cells. Dendrites, on the other hand, receive signals from other neurons and transmit them to the cell body. The neurolemma is a layer of cells surrounding the axon that facilitates nerve regeneration. The synapse is the junction between two neurons where signals are transmitted through neurotransmitters.

In terms of fine motor development, what should the infant of 7 months be able to do?
- A. Transfer objects from one hand to the other and bang cubes on a table.
- B. Use thumb and index finger in crude pincer grasp and release an object at will.
- C. Hold a crayon between the fingers and make a mark on paper.
- D. Release cubes into a cup and build a tower of two blocks.
Correct Answer: A
Rationale: At 7 months old, infants are typically able to transfer objects from one hand to the other and bang cubes on a table. This demonstrates the development of their fine motor skills related to coordination, dexterity, and object manipulation. They are refining their hand-eye coordination and grasping abilities at this stage, preparing for more complex fine motor tasks in the future. The ability to purposefully transfer objects between hands and make intentional actions, like banging cubes on a table, shows the progression of their fine motor development at this age.
When administering spironolactone (Aldactone) to a client who has had a unilateral adrenalectomy, the nurse should instruct the client about which of the following possible adverse effects of the drug?
- A. Breast tenderness
- B. Increased facial hair
- C. Menstrual irregularities
- D. Hair loss
Correct Answer: C
Rationale: Spironolactone (Aldactone) is a potassium-sparing diuretic and aldosterone antagonist that is commonly used to treat conditions such as hypertension, heart failure, and edema. One of its common side effects is hormonal effects due to its antiandrogenic properties. In women, spironolactone can lead to menstrual irregularities, including amenorrhea (absence of menstrual periods) or breakthrough bleeding. Therefore, in a client who has had a unilateral adrenalectomy (removal of one adrenal gland), which can already disrupt hormonal balance, the nurse should educate the client about the potential for menstrual irregularities when taking spironolactone.
While caring for a critically ill child, the nurse observes that respirations are gradually increasing in rate and depth, with periods of apnea. What pattern of respiration will the nurse document?
- A. Dyspnea
- B. Tachypnea
- C. Cheyne-Stokes respirations
- D. Seesaw (paradoxic) respirations
Correct Answer: C
Rationale: Cheyne-Stokes respirations are characterized by alternating periods of deep, rapid breathing followed by periods of apnea. This cyclic pattern of respiration is often seen in critically ill patients and can be a sign of serious neurological or cardiac dysfunction. The nurse should document Cheyne-Stokes respirations when observing this specific breathing pattern in the child described in the scenario.
A client is undergoing test for multiple myeloma. Diagnostic study findings in multiple Myeloma includes:
- A. A decreased serum creatinine level.
- B. Bence jones protein in the urine.
- C. Hypocalcemia.
- D. A low serum protein level.
Correct Answer: B
Rationale: Diagnostic study findings in multiple myeloma often include the presence of Bence Jones protein in the urine. Bence Jones protein is a type of abnormal protein (immunoglobulin light chain) produced by the abnormal plasma cells in multiple myeloma. Its presence in the urine can be detected through urine protein electrophoresis and is a characteristic feature of the disease. Other common findings in multiple myeloma include hypercalcemia, elevated serum creatinine level, and high serum protein level due to the excess production of monoclonal immunoglobulins.
Which of the ff is a sign of urinary retention in older adults with a neurologic deficit?
- A. Amnesia
- B. Hypertension
- C. Hypotension
- D. A behaviour change
Correct Answer: D
Rationale: Urinary retention in older adults with a neurologic deficit can lead to a behavior change. This change may manifest as increased restlessness, agitation, or discomfort. It is important to be vigilant for any sudden alterations in behavior as they may indicate underlying complications such as urinary retention, which can be more challenging to identify in older individuals who may have difficulty communicating their symptoms clearly. Monitoring for behavior changes can help healthcare providers promptly address and manage urinary retention in these individuals.
