The clinical manifestations should the nurse expect are reports of leg fatigue, tortuous veins in the legs and pain in lower extremities when standing.

In addition, leg fatigue is a communal clinical manifestation triggered by venous stasis and insufficient tissue oxygenation. The vein walls deteriorate and dilate causing distended, bulging veins that look tortuous and darkened. As vein walls weaken and dilate venous pressure increases and the valves turn out to be useless in which vein stasis and inadequate oxygenation end result is limb discomfort. The discolored toenails effect from a fungus below the nail or chronic hypoxia, not varicose veins, confined to a small area of heat in a calf is a mark of thrombophlebitis and reddened zones on a leg are symptomatic of thrombophlebitis.

Answer:

See explanation below.

Explanation:

<em>Study Design - Partially double-blinded study</em>

  • The <u>cohort study </u>will be composed of 80 adults (aged ≥18 years) with a clinical diagnosis of constant coughing present as a result of a cold, which would be measured by semiautomated ambulatory cough monitor.
  • This study will be divided into an experimental group and a control group:
  1. No medication (natural drops; <em>e.g.</em> water; saline solution) - <em>Control group </em>
  2. Cough treatment - <em>Experimental group</em>
  • Data to be collected:

Participant cough will be recorded <u>every hour</u> (until 8 hours are reached) for two consecutive days (for repetitions) in both groups using semiautomated ambulatory cough monitor and analyzed statistically.

  • Observations:

Experimental group: <u>If coughing is significantly (statistical analysis) reduced within the 8 hours </u>(<em>after repetitions</em>) and a symptom improvement is observed, <u>the hypothesis that cough drops are effective is valid</u>.

Control group: To determine that cough drops treatment is effective, the no-treatment group should score worst and participant should not show significant improvement.

*<em>In scientific experiments, repetitions are important to prevent bias and error.</em>

A musk ox and the Alstroemeria flower have physical structures and organs that have similar functions. Provide two examples of s
gladu [14]

Answer:

Mammals

Birds

Explanation:

The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.

Organs are the structures that made up of two or more tissues organized to carry out a particular function.

An organ or bone that appears in different animals with same function is called homologous structure.

Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.

Different animals have bones that appear very similar in form or function and seem to be related.

Examples

The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.

The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job.  For example, the wings of bats and birds.
