Nursing Elites

1. While explaining an illness to a 10-year-old, what should the nurse keep in mind about the cognitive development at this age?

• A. They are able to make simple associations of ideas
• B. They are able to think logically in organizing facts
• C. Interpretation of events originates from their own perspective
• D. Conclusions are based on previous experiences

Correct answer: B

Rationale: At the age of 10, children are in the concrete operations stage according to Piaget. They are capable of mature thought when allowed to manipulate and organize objects. This means they can think logically, organize facts, and understand cause-and-effect relationships. Choices A, C, and D are incorrect. While simple associations of ideas may occur, the key cognitive ability at this stage is the capacity for logical thought and organization of information. Interpretation of events from their own perspective is more characteristic of younger children, and conclusions based on previous experiences are more aligned with older children or adults.

2. What does preload refer to?

• A. The volume of blood entering the left side of the heart
• B. The volume of blood entering the right side of the heart
• C. The pressure in the venous system that the heart must overcome to pump the blood
• D. The pressure in the arterial system that the heart must overcome to pump the blood

Correct answer: B

Rationale: Preload refers to the volume of blood that enters the right side of the heart. This volume stretches the fibers in the heart before contraction. Preload is an essential factor in determining the force of ventricular contraction. Choices A, C, and D are incorrect. Choice A is incorrect because preload is specifically related to the volume of blood entering the right side of the heart. Choices C and D are incorrect as they refer to afterload, which is the pressure that the heart must overcome to pump blood out of the ventricles into the systemic or pulmonary circulation.

3. A patient suffering from hyperglycemia would be experiencing:

• A. Low blood sugar
• B. High blood sugar
• C. Normal blood sugar
• D. None of the above

Correct answer: B

Rationale: Hyperglycemia is a condition characterized by high blood sugar levels. In this state, there is an excess of glucose in the bloodstream. Patients with hyperglycemia are often diagnosed with diabetes. The term 'hyperglycemia' specifically refers to elevated blood sugar levels. Therefore, the correct answer is 'High blood sugar.' Choices A, C, and D are incorrect because hyperglycemia indicates elevated blood sugar levels and not low or normal levels.

4. Digestion, elimination, and ___________ are the three functions of the digestive system.

• A. constriction
• B. relaxation
• C. absorption
• D. peristalsis

Correct answer: C

Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream. Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.

5. You have been assigned to take an apical pulse for one of the patients on the nursing unit. How will you do this?

• A. You will place the stethoscope over the heart and listen for any irregular beats.
• B. You will place the stethoscope over the heart and count the beats per minute.
• C. You will place your fingertip over the patient's wrist and feel for any irregular beats.
• D. You will place your fingertip over the patient's wrist and count the beats per minute.

Correct answer: B

Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.
