Question 23
Regular
A client, newly prescribed a low-sodium diet due to hypertension, is asking for help with meal choices. The client names four favorite meal choices. Which selection would be best?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Green pepper stuffed with diced tomatoes and chicken. This meal is optimal for a low-sodium diet as it features fresh vegetables and lean protein, minimizing added salt while providing essential nutrients beneficial for managing hypertension.
A: Toasted cheese sandwich on whole wheat toast with tomato soup. This option likely contains high sodium levels from cheese and processed soup, making it unsuitable for someone on a low-sodium diet.
B: Creamed chipped beef over toast with mashed potatoes. This dish typically has high sodium content from processed meat and gravy, which contradicts the client's need for a low-sodium meal.
C: Hot dog with ketchup and relish on whole wheat bun. Hot dogs and condiments are notoriously high in sodium, undermining the dietary requirements necessary for effectively managing hypertension.

Question 24
Regular
The nurse would screen a client from which ethnic background for hypertension at an early age?
Correct!
Incorrect
The correct answer is: D
Rationale
The nurse would screen a client from the population of African descent for hypertension at an early age. Individuals of African descent exhibit a higher prevalence of hypertension, often developing it earlier in life compared to other ethnic groups, necessitating proactive screening to manage health risks effectively and promote better long-term outcomes in this population.
A: Asian population Cultural dietary habits among many Asian populations may contribute to lower hypertension rates, thus not warranting early screening for hypertension compared to higher-risk groups like those of African descent.
B: Japanese population While Japanese individuals can experience hypertension, the incidence is generally lower and typically occurs at an older age, making early screening less critical than for populations of African descent.
C: Mexican population Although the Mexican population has some hypertension risk, the urgency for early screening is less pronounced than in populations of African descent, where hypertension develops more frequently and at younger ages.

Question 25
Regular
The nurse is caring for a client with essential hypertension. The nurse reviews lab work and assesses kidney function. Which action of the kidney would the nurse evaluate as the body's attempt to regulate high blood pressure?
Correct!
Incorrect
The correct answer is: B
Rationale
The kidney excretes sodium and water. This action helps reduce blood volume and consequently lowers blood pressure, functioning as a regulatory mechanism in response to essential hypertension.
A: The kidney retains sodium and water. Retaining sodium and water would increase blood volume, potentially worsening hypertension rather than regulating it, contradicting the body's need to lower blood pressure.
C: The kidney retains sodium and excretes water. Retaining sodium while excreting water would lead to an imbalance that could elevate blood pressure further, which is not a regulatory response.
D: The kidney retains water and excretes sodium. Retaining water while losing sodium does not effectively lower blood volume, thus failing to address the regulation of high blood pressure.

Question 26
Regular
Which of the following nursing diagnoses is the nurse most correct to choose when caring for a client with long-standing hypertension?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Altered Tissue Perfusion. This diagnosis is appropriate due to the chronic nature of hypertension, which can lead to impaired blood flow and oxygen delivery to tissues, resulting in potential complications.
A: Impaired Gas Exchange. This option does not directly relate to hypertension, as it primarily pertains to respiratory functions and is not a primary concern for clients with high blood pressure.
B: Activity Intolerance. While this may be a consideration, it does not specifically address the physiological changes and risks associated with long-standing hypertension, making it less relevant for this diagnosis.
D: Risk for Decreased Cardiac Output. This diagnosis focuses on potential cardiac output issues; however, altered tissue perfusion is a more direct consequence of chronic hypertension, making it a more suitable choice.

Question 27
Regular
The nurse is caring for a client with hypertension. The nurse is correct to realize that a 24-hour urine is ordered to determine if the cause of hypertension is related to the dysfunction of what?
Correct!
Incorrect
The correct answer is: B
Rationale
The adrenal gland. The 24-hour urine test assesses hormone levels, particularly catecholamines and cortisol, produced by the adrenal glands. Abnormalities in these hormones can indicate conditions like pheochromocytoma, leading to hypertension.
A: Thyroid gland. While thyroid dysfunction can affect blood pressure, the 24-hour urine test specifically targets adrenal gland function, making it less relevant for identifying hypertension causes.
C: Pituitary gland. Although the pituitary regulates hormones influencing blood pressure, it is not directly evaluated through a 24-hour urine collection, which focuses on adrenal gland activity.
D: Thymus. The thymus primarily functions in the immune system and does not play a significant role in regulating blood pressure, making it unrelated to the assessment of hypertension causes.

Question 28
Regular
The nurse is teaching a client about hypertension and the effects on the left ventricle. What diagnostic test will the nurse describe?
Correct!
Incorrect
The correct answer is: A
Rationale
Echocardiography provides vital insights into the heart's structure and function, particularly assessing the left ventricle's size and performance in patients with hypertension, making it the most relevant diagnostic test.
B: Computed tomographic (CT) scan primarily focuses on imaging cross-sectional views of the body's organs and tissues, lacking the specific cardiac functional assessment needed for hypertension-related left ventricle evaluation.
C: Fluorescein angiography is designed to visualize blood flow in the retina and does not offer any relevant information regarding the heart or its chambers in hypertension cases.
D: Positron emission tomography (PET) scan is used for metabolic and functional imaging of tissues, but it does not specifically assess structural changes in the left ventricle due to hypertension.

Question 29
Regular
The nurse is teaching a client about chronic untreated hypertension. What complication will the nurse explain to the client?
Correct!
Incorrect
The correct answer is: C
Rationale
Chronic untreated hypertension can lead to a stroke. This occurs due to prolonged high blood pressure damaging blood vessels, increasing the risk of clots or ruptures that can impair brain function.
A: peripheral edema Excess fluid retention typically results from heart failure or kidney issues, not directly from hypertension alone, making this option less relevant to chronic high blood pressure complications.
B: right-sided heart failure While untreated hypertension can contribute to heart failure, it primarily leads to left-sided failure first; right-sided failure is a secondary consequence, not a direct complication.
D: pulmonary insufficiency This condition generally arises from respiratory disorders rather than hypertension, as high blood pressure does not directly compromise lung function or oxygen exchange in the pulmonary system.
