An 87-year-old woman had to double up her dosage of morphine 60mg into 120mg twice a day, in addition to another 10mg oral Morphine 6 times a day. What is the best method of management?
Your Answer: 90mg MR morphine plus 30mg every 4 hours
Correct Answer: Subcutaneous morphine infusion
Explanation:Stable dose of Morphine is essential for chronic cases of pain that are non-malignant in origin. Using the SC route avoids having to intravenously cannulate a patient and allows for a continuous infusion of drugs over a calculated period of time providing constant dosing A significant advantage is that plasma levels of a drug are much more stable, and appropriate symptom control can be achieved without the toxic effects of the peaks and troughs resulting from episodic drug administration.

Question 3
Incorrect

An 86 year old woman accidentally inhaled her hearing aid due to her advanced Alzheimer's dementia. Upon clinical examination, her respiratory rate is found to be 35, and thus a bronchoscopy is recommended. According to which of the following would you obtain consent for this patient?
Your Answer: Relatives/next of kin will have to consent for the patient
Correct Answer: The procedure does not require a written consent
Explanation:This is an emergency case regarding a patient with impaired cognitive functioning. This is why the procedure does not require a written consent. In any other case where the patient has a normal mental capacity, the consent would be obtained as an informed written consent. In this case however, the suggested procedure is almost a matter of life and death, the doctor being required to act on behalf of the patient to her optimal advantage. Under English law no other person can consent to treatment on behalf of an adult, though it is desirable that next of kin are consulted before treating an adult without consent. Recent legislation gives legal authority to people appointed by the patient, or by the state, or a relative or carer, to consent (or refuse) on behalf of the patient. A mini-mental score may not adequately identify those unable to give consent.

Question 4
Correct
-
An 82 year old male woke up experiencing incoherent speech - he is also finding it difficult to find the right words to explain his thoughts. Doctors have examined him, and everything else appears to be normal. They have also found that his comprehension is good. From the list of options, choose the anatomical site which in this instance, is most likely affected.
Your Answer: Broca’s Area
Explanation:The combination of good comprehension but poor speech quality in this patient is consistent with damage to the Broca’s area. The Wernicke’s area is responsible for the understanding of speech, and so is not consistent with this patient.

Your Answer: Loss of control of bladder

Question 6
Incorrect
-
A 62 year old female has complained she feels unsteady when she is walking. She is examined and is found to have pyramidal weakness of her left lower leg. She also has reduced pain and temperature sensation on her right leg and right side of her torso up to the umbilicus. Her joint position sense is also impaired in her left big toe but is found to be normal elsewhere. She has definite left extensor plantar response, and the right plantar response is equivocal. Where is the lesion?
Your Answer: Midline mid-thoracic cord
Correct Answer: Left mid-thoracic cord
Explanation:In Brown-Sequard syndrome, there is paralysis and loss of proprioception, which occurs on the same (ipsilateral) side of the body, as the lesion. Loss of pain and temperature sensation, therefore, occurs on the opposite (contralateral) side of the body as the lesion.
