The hallmark of a subarachnoid hemorrhage is the very sudden onset of a severe headache. The headache is often described as the "worst headache of my life." A CT scan will detect a subarachnoid hemorrhage in more than 95% of cases. When the history suggests subarachnoid hemorrhage and the CT scan fails to detect bleeding, a lumbar puncture is mandatory. The lumbar puncture will yield bloody cerebrospinal fluid in subarachnoid hemorrhage. Outpatient MRI or repeat CT scan in 48 hours would create a potentially harmful delay in diagnosis. CBC with differential may be ordered but will not confirm the suspected diagnosis. Treatment with Imitrex is contraindicated in the presence of a potential cerebrovascular syndrome.

A 41-year-old woman presents to the emergency department complaining of a sudden onset of the "worst headache of my life." A stat computed tomography (CT) scan of her head is found to be normal. The next appropriate step in the diagnosis of this patient would be

A

outpatient magnetic resonance imaging (MRI) of the brain

B

complete blood cell count (CBC) with differential

C

injection of sumatriptan (Imitrex)

D

lumbar puncture

E

repeat CT scan in 48 hours

Answers

Answer 1

In this scenario, the patient's history suggests a possible subarachnoid hemorrhage, despite a normal CT scan. The next appropriate step in the diagnosis would be a lumbar puncture.

This is because a CT scan may not detect a subarachnoid hemorrhage in its early stages, and a lumbar puncture can confirm the presence of blood in the cerebrospinal fluid. It is important to note that ordering a CBC with differential may not confirm the suspected diagnosis of subarachnoid hemorrhage. Additionally, treatment with Imitrex is contraindicated in the presence of a potential cerebrovascular syndrome. Outpatient MRI or repeat CT scan in 48 hours would create a potentially harmful delay in diagnosis and treatment, as subarachnoid hemorrhages require immediate medical attention.

Which of the following positions would demonstrate the right lumbar zygapophyseal articulations closest to the IR?
A.LAO
B.RAO
C.LPO
D.RPO

Answers

The answer is D. RPO (Right Posterior Oblique) position would demonstrate the right lumbar zygapophyseal articulations closest to the IR.

The position that would demonstrate the right lumbar zygapophyseal articulations closest to the IR is the LPO (left posterior oblique) position. In this position, the patient is lying on their left side with the left posterior aspect of the body closest to the image receptor (IR), while the right side is further away. The obliquity of the position causes the right lumbar zygapophyseal joints to be closer to the IR and more perpendicular to the x-ray beam, resulting in better visualization of the joint spaces. The RAO (right anterior oblique) position would show the left lumbar zygapophyseal joints closest to the IR.

What blood pressure medication is most proven to have the greatest beneficial effect in controlling HTN in diabetes?

Answers

There are several types of blood pressure medications that are proven to have beneficial effects in controlling hypertension (HTN) in diabetes, including ACE inhibitors, ARBs, calcium channel blockers, and diuretics.

However, research suggests that ACE inhibitors and ARBs may be the most effective in reducing the risk of cardiovascular events and kidney damage in individuals with both diabetes and HTN. These medications work by blocking the effects of hormones that can raise blood pressure, as well as promoting vasodilation and reducing inflammation.

Ultimately, the choice of medication will depend on individual factors such as medical history, coexisting conditions, and potential side effects. It's important to work closely with a healthcare provider to determine the most appropriate treatment plan for managing HTN in diabetes.

a patient has experienced chronic blood loss and iron deficiency from peptic ulcer disease which type of anemia would the nurse anticipate?

Answers

The nurse would anticipate the patient to have microcytic hypochromic anemia due to chronic blood loss and iron deficiency caused by peptic ulcer disease.

This type of anemia occurs when there is a deficiency of iron, which is needed for the production of hemoglobin. The lack of hemoglobin in the red blood cells leads to the cells being smaller (microcytic) and paler (hypochromic) than normal.

Peptic ulcer disease can cause chronic blood loss in the gastrointestinal tract, leading to a reduction in iron levels and subsequent anemia. Treatment would involve identifying and treating the underlying cause of the peptic ulcer disease, such as using antibiotics to eradicate H. pylori or reducing the use of NSAIDs.

Additionally, the patient may require iron supplementation to replenish their iron levels and improve their anemia.

PKA, activated during hypoglycemia, inhibits __ and promotes __; protein phosphatase, activated during fed state, promotes __ and inhibits __

glycogen synthase
glycogen phosphorylase
glycogen synthase
glycogen phosphorylate

Answers

PKA is an enzyme that plays a crucial role in regulating cellular functions. During hypoglycemia, PKA is activated to maintain glucose homeostasis in the body. One of the important targets of PKA is glycogen synthase, an enzyme responsible for glycogen synthesis. PKA inhibits glycogen synthase, thereby preventing glycogen synthesis and promoting gluconeogenesis. This helps to increase blood glucose levels during hypoglycemia.

On the other hand, protein phosphatase is another enzyme that plays a critical role in glucose homeostasis. During the fed state, protein phosphatase is activated to promote glycogen synthesis and inhibit gluconeogenesis. One of the key targets of protein phosphatase is glycogen synthase. It activates glycogen synthase, thereby promoting glycogen synthesis and storage.

In summary, PKA and protein phosphatase play opposite roles in regulating glycogen synthesis. PKA inhibits glycogen synthase during hypoglycemia to promote gluconeogenesis and increase blood glucose levels, whereas protein phosphatase activates glycogen synthase during the fed state to promote glycogen synthesis and storage. This ensures that glucose levels are maintained within a narrow range to meet the energy demands of the body.

What is term for photons that hit tissue and change direction (scatter) and some energy is lost?

Answers

The term for photons that hit tissue and change direction (scatter) and some energy is lost is Compton scattering. This phenomenon occurs when high-energy photons, such as X-rays or gamma rays, collide with the electrons in an atom's outer shell. The collision causes the photon to lose some of its energy, and the electron is ejected from the atom.

The scattered photon then moves in a new direction with less energy than the original photon, and some of the energy is transferred to the ejected electron. Compton scattering is an important process in medical imaging, as it helps to create contrast in X-ray images by highlighting areas where photons have been scattered more or less than others.

It is important to note that while Compton scattering can be useful in medical imaging, it can also be harmful to human tissue. The scattered photons can cause damage to DNA, which can lead to mutations and potentially cancer. Therefore, it is important to use caution and minimize exposure to ionizing radiation when undergoing medical imaging procedures.
