Nursing Elites

1. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

• A. MAP is the pressure of the arterial pulse.
• B. MAP reflects the stroke volume of the heart.
• C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
• D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

2. When cleansing the genital area during perineal care, the nurse should _____________.

• A. cleanse the penis with a circular motion starting from the base and moving toward the tip.
• B. replace the foreskin after it has been pushed back to cleanse an uncircumcised penis.
• C. cleanse the rectal area first and then clean the patient's genital area.
• D. use the same area on the washcloth for each washing and rinsing stroke for a female resident.

Correct answer: B

Rationale: During perineal care, when cleansing the genital area of an uncircumcised male patient, it is crucial to retract the foreskin to clean the area underneath. This helps in the removal of smegma, a substance that can accumulate and lead to bacterial growth and infection if not cleaned properly. The foreskin should then be replaced back to its original position after cleaning to ensure proper hygiene and prevent any potential complications. Choices A, C, and D are incorrect because they do not address the specific care required for an uncircumcised penis, which involves retracting and replacing the foreskin.

3. A patient who is displaying the defense mechanism of Compensation would:

• A. Refuse to hear unwanted information.
• B. Transfer feelings of negativity to someone else.
• C. Overemphasize behaviors which accommodate for perceived weaknesses.
• D. Place blame on others for personal actions or mistakes.

Correct answer: C

Rationale: The correct answer is 'Overemphasize behaviors which accommodate for perceived weaknesses.' Compensation involves overemphasizing or exaggerating a particular behavior or trait to make up for or cover up perceived weaknesses in oneself. This defense mechanism allows individuals to focus on their strengths rather than acknowledging their shortcomings. Choices A, B, and D are incorrect. Refusing to hear unwanted information relates more to denial, transferring feelings of negativity to someone else is projection, and placing blame on others is an example of the defense mechanism known as externalization.

4. Which of the following sets of word parts means 'Pain'?

• A. dynia and -algia
• B. a- and an
• C. ia and -ac
• D. pathy and -osis

Correct answer: A

Rationale: The correct answer is 'dynia and -algia.' The word parts 'dynia' and '-algia' specifically relate to pain. 'Dynia' refers to pain, and '-algia' also denotes pain. Therefore, when combined, they form the meaning 'pain.' Choices B, C, and D are incorrect because 'a-' and 'an' do not relate to pain, 'ia' and '-ac' do not specifically convey pain, and 'pathy' and '-osis' are not word parts that directly signify pain.

5. In a 68-year-old man, a gradual loss of hearing is known as _____________.

• A. presbycusis
• B. xerostomia
• C. myopia
• D. presbyopia

Correct answer: A

Rationale: The correct answer is 'presbycusis.' Presbycusis is the age-related gradual loss of hearing ability, commonly seen in the elderly population. Xerostomia refers to dry mouth, myopia is nearsightedness, and presbyopia is the age-related loss of the eye's ability to focus on close objects. Given Mr. Roberts' age and symptom of gradual hearing loss, presbycusis is the most likely diagnosis. Xerostomia, myopia, and presbyopia do not match the sensory change described in the question, making them incorrect choices.
